Drop eslint-config-airbnb* presets

[frantic1048]

The eslint-config-airbnb primarily focuses on legacy JavaScript code, making it ill-suited for our modern TypeScript codebase that requires significant adjustments. We may consider removing it and maintaining our own configuration to enhance ergonomics.

Since we already have a snapshot test for the rules, we can utilize it to ensure that no rules are changed after removing the eslint-config-airbnb* dependencies. Subsequently, we can enhance the rules further.

Steps:

• [x] 1. Extract the used eslint-config-airbnb* rules into our repository. https://github.com/RightCapitalHQ/frontend-style-guide/pull/160
• [x] 2. Remove redundant/unnecessary configurations/dependencies. https://github.com/RightCapitalHQ/frontend-style-guide/pull/166
  • Reduce redundant rule overrides.
  • Remove style related rules that conflict with Prettier.
  • Remove unnecessary legacy ESLint(<8) config.
• [ ] 3. (Move to separate issue?)Reorganize the rules.
  • Remove the rules that already included in ESLint's recommended preset. Adapt to ESLint's recommended preset.
