👷 CI to report graphQL schema changes upon PR

[ccamel]

Idea

Every time the graphQL schemas change, we need to be informed if the change is breaking or non-breaking.

Proposal

The proposal is to automatically post a comment on the PR whenever there are modifications to the GraphQL schemas. This comment will provide information about whether the changes are breaking or non-breaking.

To implement this, we can use the actions/graphql-inspector GitHub action, which will take care of the inspection of the schemas when the PR is opened.

Todo

• Assess the suitability of actions/graphql-inspector for our requirements.
• Implement a new job in the lint workflow responsible for posting a descriptive comment regarding any changes made to the GraphQL schemas.
• Conduct testing to ensure the functionality works as intended.
