@rtk-query/codegen-openapi support for "pattern" in outputFile

[RhysOnlyBetter]

Currently the "pattern" value in an openapi property as described here is ignored in the codegen output. It would be great if this could be added as a value or comment in the outputFile to make it easier to align regex with api expectations

Any updates on this?

@remkodejong there's been no discussion from anyone or comments from us, so no :)

As always, PRs would be welcome!
