docs/website: simplify section on Git repo

Now that the snapshot tarball section is gone, the "Source code" block
has only one sub-block "Repository" which makes it look odd. So bring
the sub-block content into the parent block, and rename this parent
block "Git repository".

As this requires re-indenting the whole HTML soup, take advantage of
this to use <p>...</p> in a more correct manner.
