init scaffolding should prompt for installing common plugins (TypeScript and markdown)

[thescientist13]

Summary

Coming out of #1253, I think to continue making the Init scaffolding tool more valuable, we should add prompts to auto install / configure

• TypeScript
• markdown (should probably be done after standalone rehype based markdown plugin #1247 )

Something like

➜  Workspace npx @greenwood/init@latest
Need to install the following packages:
  @greenwood/[email protected]
Ok to proceed? (y) y
-------------------------------------------------------
Initialize Greenwood Template ♻️

Details

In addition, we should probably start prompting for an output directory, or at least defaulting to

? Project name you like to use markdown? (type)
❯ my-app (default)

We might also want to move the template prompt to a selector as well, just to keep the experience consistent.

? Would you like to use a template? (Use arrow keys)
❯ No (default)
❯ Blog
❯ ...

If possible, we should try and tackle #1050 / #787 at the same time
