[Task]: Improve speed of ESLint

[maxwellmattryan]

Task description

While usually the linter is running locally with cached data to improve the speed, it still takes a considerable amount of time on fresh commits to PRs, so it would be worth investigating how to speed it up.

Requirements

TBD

Creation checklist

• I have assigned this task to the correct people
• I have added the most appropriate labels
• I have linked the correct milestone and/or project
