The version is not added correctly

[Umberto Baldi]

Apparently, the ${GITHUB_REF##*/} variable is not expanded correctly in the release CI. This bug has been introduced in #4

./rp2040load -v
rp2040load ${GITHUB_REF##*/} - compiled with go1.16.2

[Per Tillisch]

I think it is caused by the environment variable having been wrapped in single quotes:

rp2040tools/.github/workflows/release.yml

Line 166 in 8f73b2f

 run: go build -ldflags '-X main.version=${GITHUB_REF##*/}'
