Initial edits to Overview and Commands

[alvinj]

These are my initial edits to the Overview page and all of the pages in the Commands section.

A few notes to go along with this:

• The source code on lines 28+ of package.md is commented-out
• In package.md, the default format is called a "lightweight launcher JAR" and then later as "bootstraps", so I added the bootstrap term earlier
• The latest tag is mentioned on line 88 of package.md but isn’t used in the command
• The DEB/RPM/PKG/MSI links on lines 166+ of package.md may be broken
• The 'pkg' command on line 241 of package.md may be wrong
• The 'msi' command on line 261 of package.mdmay be wrong
• In fmt.md, it talks about scalafmt.conf files (under Dialects), but under Current Limitations it says they aren’t supported (lines 23+)
• Reading the docs in linear order, in clean.md, line 6, I don’t yet know what the .scala directory is
• I’m not sure if what I wrote at the beginning of setup-ide.md is correct (about manually running the command)

I've resolved the conflicts.

As for the notes:

The source code on lines 28+ of package.md is commented-out

This is our current way to show the output of the command. @MarcinAman is working on a proper UI widget.

The latest tag is mentioned on line 88 of package.md but isn’t used in the command

It is added by docker (but we wanted to mention it explicitly)

The DEB/RPM/PKG/MSI links on lines 166+ of package.md may be broken

Fixed that

In fmt.md, it talks about scalafmt.conf files (under Dialects), but under Current Limitations it says they aren’t supported (lines 23+)

I've reworded the section to be more clear.

Looks ok.
