Airtable switch from API key to personal access token

[crayolakat]

Fixes #788

The authentication process using Airtable API key vs personal access token is the same. Switching the name from api_key to personal_access_token to reflect the fact that Airtable will be deprecating API keys and a personal access token should be used instead: https://community.airtable.com/t5/announcements/new-api-capabilities-now-in-ga-and-upcoming-api-keys-deprecation/ba-p/141824

This is a breaking change, so we should merge it into the major-release branch instead of main. (Here is some more information on that: https://www.parsonsproject.org/pub/parsons-semantic-versioning/release/1)

@Jason94 Thanks for letting me know! I've switched the base branch

[Jason94]

@crayolakat It looks like you're accidentally bringing some other commits from the main branch with you. Do you know how to rebase? If you rebase onto the major-release branch it should be fine. If not just let me know, and I can merge main into major-release and it should be fine.

Oops thanks for flagging it should be fixed now! @Jason94

Looks good to me!
