[Lint] Exclude js and css from EOF fixer

- When running pre-commit on all files it is picking up minified js and
  css files. Since prettier will format correctly the source files ignore
  them in end-of-file fixer.
- The template files in web docs can be ignored too.
- Removed the unneeded `pre-commit-hooks` dependency as pre-commit
  resolves that itself.
- Include files fixed by pre-commit.
