web/components: raise the repo panel metadata to the base size
the commits, branches and tags panels paired 16px primary lines with 12px
metadata, which read as an afterthought next to them. move the metadata to
text-paragraph-regular (14px, the base body size) so each panel keeps a 16/14
hierarchy instead of jumping 16/12.
