Fix CI upload assets tag matching
The previous version would search for the last tag by matching the
beginning of the tag name. By explicitly searching for the trailing `"`
with grep, an exact tag match is now enforced.

Since releases like v1.2.3 always match the beginning of their RCs
(v1.2.3-rc4), this makes sure that the assets aren't pushed to the
previous release.
