all: replace html/template by text/template

Neither `cue add --list` nor cue/stats need to deal with HTML,
so text/template is the right one to use.
It's entirely possible that gopls or goimports added html/template
since they both provide the same package name and API interface.

A small yet nice win as well is a ~200KiB size shaving,
since html/template is no longer imported at all:

    $ du -b cue-before cue-after
    25738624	cue-before
    25535404	cue-after
