chore: replace given and family names with first and last names (#11343)

# Which Problems Are Solved

Naming inconsistency w.r.t the usage of Given Name / Family Name instead
of First Name / Last Name

# How the Problems Are Solved

* By replacing given and family names with first and last names in UI
and docs (not in the API definitions)
* Updated translations in multiple languages to first and last names
instead of given/family names

# Additional Changes
* Add `internal/**/*.yaml` path to the nx sources input to rebuild the
binary upon changes to these files
* Fix failing unit tests in `user_notifier_legacy_test.go` by updating
`Passwordless` with `Passkey`

# Additional Context
- Closes https://github.com/zitadel/zitadel/issues/11308
