Docs: Easy flow for macOS use

[jasikpark]

I think this is mostly covered by your docs, but not entirely clearly, since I originally thought I needed to manage java.

I got setup w/ this tool by:

1. Installing the extension from the VSCode extension marketplace
2. "Using" the linter for a few days while it was unattached to a service
3. Actually reading the README and realizing I needed to install the languagetools service
4. Running brew install languagetools which installed the bottle version of languagetool, rather than the app
5. Running brew services restart languagetools which started up the languagetools service that got installed by homebrew with the tool
6. CTRL+S on the MDX file I had open in VSCode, and I'm off to the races!!

Thanks for working on this tool! So much better than cspell and trying to manage an ever-growing dictionary of words cspell doesn't know.

Thanks so much for the feedback! The docs definitely need some work. I'll get this incorporated as soon as I'm able. Might even pop open a "getting started" screen to give folks platform-specific instructions as install time. Assigned to myself, and leaving it open to keep this on my radar.

This extension has been really great! It stumbles over quite a bit of MDX syntax, but it's nice to have the grammar and spelling checks when it's available -- "add to workspace ignores" is much more enjoyable than manually editing a cspell config too :p
