Update non PEP 440 wheel filename deprecation notice

[notatallshaw]

As requested in #12918 (comment) this creates an issue and points to the deprecation notice to that issue (#12938).

Further, upon testing pip main for a little bit I found several packages that use _ to separate the version and build number, which is valid, but the deprecation was pretty noisey as the current logic can't distinguish this, so I updated the deprecation to not fire unless parse_wheel_filename identified it as invalid.

E.g

$ pip install --dry-run marshmallow==1.0.0
  DEPRECATION: Wheel filename 'marshmallow-1.0.0_a-py2.py3-none-any.whl' uses an invalid filename format, as the version part '1.0.0_a' is not correctly normalised, and contains an underscore character. Future versions of pip may fail to recognise this wheel. pip 25.1 will enforce this behaviour change. A possible replacement is rename the wheel to use a correctly normalised version part (this may require updating the version in the project metadata).

Collecting marshmallow==1.0.0
  Downloading marshmallow-1.0.0-py2.py3-none-any.whl.metadata (15 kB)
Downloading marshmallow-1.0.0-py2.py3-none-any.whl (45 kB)
Would install marshmallow-1.0.0
