Dependabot schema is missing pre-commit in package-ecosystem enum

[sebp]

The bundled schema for dependabot is missing pre-commit in the package-ecosystem enum

https://github.com/python-jsonschema/check-jsonschema/blob/main/src/check_jsonschema/builtin_schemas/vendor/dependabot.json#L648-L680

pre-commit is a supported value according to
https://docs.github.com/en/code-security/reference/supply-chain-security/dependabot-options-reference#package-ecosystem- and is included in the schema https://www.schemastore.org/dependabot-2.0.json

Yep! This had to be held back for a bit due to some issues with the dependabot schema, but those have been resolved so we'll have this in the next release. I can push that through soon.
