Had to remove these comments as the JSON format does not allow comments (pyright seems to use a stricter parser now)

what happens if you dont upgrade pyright?

Upgrading pyright is not needed for this PR. Just upgraded it because there is a newer version.

can you add a comment on why this is necessary? e.g. i think once Self is available we can swap this out?

Yes, this can be removed when we can use Self. If we want to link two parameters to be of the same NDFrame (sub-class) NDFrameT is enough, but if we have two pairs, we need to use a second TypeVar for the second pair. Otherwise, all four parameters are bound to the same (sub)class.

i know, im asking for a comment in the code to that effect

Added a comment. I realized that we cannot remove it when Self is available as Self doesn't help _align_as_utc.

Probably better to move it to pandas._typing since this will not be a temporary fix.

i think when the time comes we can make _align_as_utc a NDFrame method
