templates: reword 'back to filelog' link anchor text

This anchor text is problematic in two ways: first, the "back to" part
assumes that you got to the page showing it via the filelog. This is
not necessarily true, as there are other ways to get to that view
besides the filelog view, such as for example following the history of
lines from a file. Second, it uses "filelog" jargon, which refers to
how each file has its own revlog. This is internal jargon that has no
business being exposed to the end user.

I just reworded this template to improve understanding.
