Improve documentation for select() (#14769)

* Reference documentation that explains when to use Label rather than a label string. * Remove mention of constraint_settings as they can't be used as select keys. Closes #14458. PiperOrigin-RevId: 420129541 (cherry picked from commit 67a133b) Co-authored-by: Fabian Meumertzheim <[email protected]>
