chore: set temci tags for the radar bench script (#10527)

The radar bench scripts at
https://github.com/leanprover/radar-bench-lean4/ split up the benchmarks
between the two runners based on the tags: One runner filters by the tag
`stdlib` while the other filters by the tag `other`. Only benchmarks
using one of these tags will be run, and any benchmark tagged with both
will waste electricity.

As far as I know, the tags are unused otherwise, so I just replaced all
the old tags.
