Add linter to Chrome Extension (#4044). (#4174)

* feat: configure eslint rules by replicating those in the twenty-front package and introduce scripts for linting, formatting code and removing build output

* fix: ensure each file of the extension package satisfies linting rules and disable some rules where necessary

* fix: update relative imports to absolute imports throughout extension code with the defined tilde and at symbols

* fix: import the updated ui module from the front package to the chrome extension package to prevent eslint rules from breaking subject to the recent merged changes into main

* fix: commit the case change for files that were missed by Git in the earlier commits due to default configuration
