Fix issues with github actions

[IanMadd]

Description

Fix the GitHub actions

• the labeler action runs from the main branch, but was updated with breaking changes so now it blows up on every PR. This pins it to V4 of the labeler.
• I replaced the cspell.json with a YAML file so it's easier to read. This update should pull the correct file now.
• update other action deps
