Add support for not following symlinks in `pathlib.Path.copy()`.
On Windows we add the `COPY_FILE_COPY_SYMLINK` flag is following symlinks is disabled. If the source is symlink to a directory, this call will fail with `ERROR_ACCESS_DENIED`. In this case we add `COPY_FILE_DIRECTORY` to the flags and retry. This can fail on old Windowses, which we note in the docs.
No news as `copy()` was only just added.
The `inspect.ismethoddescriptor()` function did not check for the lack of
`__delete__()` and, consequently, erroneously returned True when applied
to *data* descriptors with only `__get__()` and `__delete__()` defined.

Add thread-safety clarifications to the SSLContext documentation. Per the issue:
This issue has also come up [here](https://github.com/psf/requests/pull/6667) where the matter was clarified by @tiran in [this comment](https://github.com/psf/requests/pull/6667):
> `SSLContext` is designed to be shared and used for multiple connections. It is thread safe as long as you don't reconfigure it once it is used by a connection. Adding new certs to the internal trust store is fine, but changing ciphers, verification settings, or mTLS certs can lead to surprising behavior. The problem is unrelated to threads and can even occur in a single-threaded program.
This matches the output behavior in 3.10 and earlier; the optimization in 3.11 allowed the zlib library's "os" value to be filled in instead in the circumstance when mtime was 0. this keeps things consistent.
Add a `Path.copy()` method that copies the content of one file to another.
This method is similar to `shutil.copyfile()` but differs in the following ways:
- Uses `fcntl.FICLONE` where available (see GH-81338)
- Uses `os.copy_file_range` where available (see GH-81340)
- Uses `_winapi.CopyFile2` where available, even though this copies more metadata than the other implementations. This makes `WindowsPath.copy()` more similar to `shutil.copy2()`.
The method is presently _less_ specified than the `shutil` functions to allow OS-specific optimizations that might copy more or less metadata.
Incorporates code from GH-81338 and GH-93152.

Add dedicated subsection for `pathlib.Path.touch()`, `mkdir()`,
`symlink_to()` and `hardlink_to()`. Also note that `open()`, `write_text()`
and `write_bytes()` are often used to create files.

Adjust DeprecationWarning when testing element truth values in ElementTree, we're planning to go with the more natural True return rather than a disruptive harder to code around exception raise, and are deferring the behavior change for a few more releases.
- Explicit list of what it does that is different from
"just return __annotations__"
- Remove reference to PEP 563; adding the future import doesn't
do anything to type aliases, and in general it will never make
get_type_hints() less likely to fail.
- Remove example, as the Annotated docs already have a similar
example, and it's unbalanced to have one example about this
one edge case but not about other behaviors of the function.

Remove the delegation of `int` to the `__trunc__` special method: `int` will now only delegate to `__int__` and `__index__` (in that order). `__trunc__` continues to exist, but its sole purpose is to support `math.trunc`.

* Passing a string as the "real" keyword argument is now an error;
it should only be passed as a single positional argument.
* Passing a complex number as the "real" or "imag" argument is now deprecated;
it should only be passed as a single positional argument.
