Fix validation regex for @requires annotation

[epdenouden]

Fixes #3459

The regex used for parsing the @require annotation would put any trailing digits of the value into the version field when there wasn't an operator. This caused trailing digits on function and extension names to be clipped.

Changes

• regex fixed
• add test for @requires function|extension someNameWithDigits123
