Preparing new release with bug fixes and docs updates

[b-per]

Changes

• #240 Add notice of deprecation for triggers.custom_branch_only for jobs and update logic to make it work even though people have it to true or false in their config. We might raise an error if the field is still there in the future.
• Update diff calculation for Extended Attributes, allowing strings which are not set with jsonencode()
• #241 Force recreation of env vars when values change to work with the recent changes in the dbt Cloud API

Documentation

• Add list of permission names and permission codes in the docs of the service_token and group
• Add info in dbtcloud_repository about the need to also create a dbtcloud_project_repository
