The "with permission from edgedb" header is confusing for people trying to reuse the code

I think Lib/asyncio/taskgroups.py should include the Apache license. The "with permission from edgedb" header is confusing for people trying to reuse the code

Currently the license header says this:

cpython/Lib/asyncio/taskgroups.py

Line 1 in 834064c

# Adapted with permission from the EdgeDB project.

I think it should include this

https://github.com/edgedb/edgedb/blob/868f3d37409435a3b6bbf8ea20ec6c193e63f076/edb/common/taskgroup.py#L1-L17

I also think there's a few changes that were backported from CPython to edgedb and then back again which need the PSF copyright header, maybe?

I specifically asked @1st1 what to do with the license/copyright notice from EdgeDb and he approved the current text. IIUC the EdgeDb CLA allows him to do that.

@graingert Please see #95847 for Yury's suggested changes.
