chore: Add release-plz schema action run (#594)

# Description

This PR makes the following changes:

- [x] Update schemas action to run on `release-plz` branches on manifest
changes only
- [x] Update schemas action to run on `main` for both manifest and Rust
changes

`release-plz` updates versions that we reference in schemas, which put
the versions in the schemas out of date. This PR updates the action to
handle version changes.

## Type of change

- [x] Refactor (non-breaking change that updates existing functionality)
