The latest website/src/errorsIdentifiers.json update shifted the source locations for the phpunit.attributeRequiresPhpVersion identifier (from 4 to 5 locations), reflecting a new error message added to AttributeRequiresPhpVersionRule in phpstan-phpunit.

After checking the updated rule source and test fixtures, the existing documentation only described the "missing operator" case, while the rule actually reports several distinct problems under one identifier. The docs were updated to cover all of them:

• Version requirement is missing operator — bare version like '8.1' with no comparison operator.
• Version requirement without operator is deprecated — same bare form when phpstan-deprecation-rules is installed.
• Version requirement is incomplete — the new message; version not in full major.minor.patch form (PHPUnit 12.5+, bleeding edge).
• Version requirement will always evaluate to false — constraint that can never match any analysed PHP version.
• Unparsable constraint strings (e.g. 'abc').

The shortDescription frontmatter was broadened to reflect the wider scope, and a fix example for writing versions in full major.minor.patch form was added.

No new identifiers required documentation — all 1097 identifiers in the JSON already have corresponding .md files.
