fix: yarn version detection

[rrooding]

Because the Yarn version does not start with a v the first character should not be cut off. This is true for all major yarn versions:

$ yarn -v
1.22.19

$ yarn set version 2
2.4.3

$ yarn set version latest
3.3.0

Because of this the action currently falls back to yarn berry and this means that if you use yarn 1.x, caching does not work:

I'm not sure how to write a test for this since the workflow works but only gives a warning in the last step.

Looks good to me.

Can you also patch the version in https://github.com/nrwl/ci/blob/main/README.md and https://github.com/nrwl/ci/blob/main/package.json to 0.11.1 so this fix is automatically accessible?
