docs: Small rendering fixes
Some small improvements for rendering of the docs.
- Remove an extra
jhbuild bootstrap
in a string. - One
::
was marked for translation. Adding an empty line after it, as is done in other places, fixed it. - Move a quotation mark that was misplaced.
- Change the links
#cfg-skip
and#cfg-partial-build
to:ref:
so they link to the anchors in the other file correctly, they previously just showed their text.
