fix(ci): fix double-v in version for v* style tags

setup-build-environment was using v${TAG#*-v} which prepended an extra
"v" when the tag already starts with "v" (e.g. v1.11 -> vv1.11).
Now uses the tag name directly for v* tags; strips name-v prefix only
for compound tags like room-server-v1.2.3.

Remove redundant Extract Version steps from the wio firmware workflow
since setup-build-environment already handles this.
