chore: remove dist files from root tsconfig + update node_modules pattern

[dougal83]

This speeds up npm run eslint, good practice

👍 LGTM

We should run the following commands to understand the impact:

1. rm .eslintcache
2. npm run eslint -- --debug
3. open .eslintcache to see what files are linted
4. change some TS files
5. npm run eslint --debug to see how the cache is leveraged to speed up eslint

Some observations:

Before I pull in this commit, dist does not seem to be linted or cached by eslint:

1. The .eslintcache file does not have any entries from dist/**/*.ts
2. npm run eslint -- --debug does not show any mentioning of dist

Fair enough, it was unnecessary in that case. TBH I didn't look deeper than comparing time npm run eslint results. Thank you for checking.
