Before this PR all .md files were targeted by the `.ignore` file, which
has bitten me on a number of occasions since .md files often contain
valuable information (e.g. the vscode extensions docs). This PR
unignores .md files while still ignoring _generated_ .md files like our
changelogs, the api-report files, and the generated docs sections.
Additionally, the `yarn format` and `yarn lint` commands were configured
slightly differently, which was confusing, so I've unified those and
simplified the lint.ts script at the same time.

Biome as it is now didn't work out for us 😢
Summary for posterity:
* it IS much, much faster, fast enough to skip any sort of caching
* we couldn't fully replace Prettier just yet. We use Prettier
programmatically to format code in docs, and Biome's JS interface is
officially alpha and [had legacy peer deps
set](https://github.com/biomejs/biome/pull/1756) (which would fail our
CI build as we don't allow installation warnings)
* ternary formatting differs from Prettier, leading to a large diff
https://github.com/biomejs/biome/issues/1661
* import sorting differs from Prettier's
`prettier-plugin-organize-imports`, making the diff even bigger
* the deal breaker is a multi-second delay on saving large files (for us
it's
[Editor.ts](https://github.com/tldraw/tldraw/blob/main/packages/editor/src/lib/editor/Editor.ts))
in VSCode when import sorting is enabled. There is a seemingly relevant
Biome issue where I posted a small summary of our findings:
https://github.com/biomejs/biome/issues/1569#issuecomment-1930411623
Further actions:
* reevaluate in a few months as Biome matures

Biome seems to be MUCH faster than Prettier. Unfortunately, it
introduces some formatting changes around the ternary operator, so we
have to update files in the repo. To make revert easier if we need it,
the change is split into two PRs. This PR has only config/package
changes and is expected to fail the CI.
## Change Type
- [x] `minor` — New feature
Adds `--cache` flag to prettier which significantly speeds up `yarn
format`:
https://prettier.io/docs/en/cli#--cache
One downside is that changing the plugins we use with prettier will not
cause the cache to invalidate. Stills seems worth it though.
> Plugins version and implementation are not used as cache keys. We
recommend that you delete the cache when updating plugins.

### Test Plan
1. Run `yarn format`
2. Run `yarn format` again, this time it should be significantly faster.
### Release Notes
- Speed up formatting of files via `yarn format`.
This diff reverts 09c36781 and tweaks how some of our linting was
working.
I'm not actually sure what caused the regression that 09c36781 was
fixing - it was something to do with typescript being used to transpile
eslintrc.js, but that being excluded from the tsconfig for those
projects. I fixed that by removing `rootDir` from those, but that
revealed some other issues with files not getting ignored correctly.
I fixed the ignoring issue with a change I've wanted to make to these
scripts for a while: only running them on files that are actually
tracked by git, instead of on everything with a relevant extension. A
side effect of that is that we have to re-implement .eslintignore
support ourselves, but that's very straight forward: the `ignore`
package that eslint uses is very easy to include.
