CONTRIBUTE: drop mention of copyright year ranges

Year ranges in copyrights were dropped in commits [1] and [2].
Verification of year ranges in copyrights was dropped from script
'scripts/copyright.pl' in commit [3].  However, the corresponding
passages in file 'docs/CONTRIBUTE.md' weren't updated.

Drop mentions of copyright year ranges from 'docs/CONTRIBUTE.md'.

[1] 2bc1d775f (copyright: update all copyright lines and remove year
    ranges, 2023-01-02)
[2] c46761bd8 (tests/http: remove year ranges from copyrights,
    2023-03-14)
[3] 0e293bacb (copyright.pl: cease doing year verifications, 2023-01-28)

Closes #11504
