Improve bad cabal-version error message (backport #9754)

[mergify]

I took a stab at improving the error message one receives for a bad cabal-version field, per the discussion here.

Example message:

Errors encountered when parsing cabal file ./records.cabal:

records.cabal:0:0: error:
Unsupported cabal format version in cabal-version field: 3.10.
Current cabal-version values are listed at https://cabal.readthedocs.io/en/stable/file-format-changelog.html.

Technically, an UX improvement, but cabal-install is not known for great UX, so we decided it'd be great to sneak in this improvement.
