Update en-us and fr-fr versions of the "Upgrade from Gogs" doc (#4618)

* Update "Upgrade from Gogs" en-us doc

- Move "Change gogs specific information" FROM/TO steps up
  to just beneath matching section header, adjust indention
  and explicitly specify syntax of code sample to provide
  highlighting

- Adjust header levels to match what appears to be the
  intended level, remove trailing decoration (see below)

- Move "Upgrading to most recent ..." section down, remove
  decoration (section header formatting likely covers this
  well enough already)
