chore(ci): RC builds: parallelize iOS and Android

[joaoloureirop]

Description

This change bumps the build version once in a dedicated job that calls update-latest-build-version.yml, then triggers iOS and Android through runway-ota-build-core in parallel. Both jobs use skip_version_bump: true and source_branch set to the version-bump commit SHA so both builds use the same tree. Downstream steps (PR comment + Slack) now require both platform jobs to succeed.
