Support semver ranges in `deno upgrade --version=`

Due to https://github.com/denoland/deno/issues/25034 I need to downgrade to Deno 1.41. I would like to use the _latest_ 1.41.x version, since that's probably better than using 1.41.0.

The only way to do so is by checking on https://github.com/denoland/deno/releases what the latest patch was, and then run `deno upgrade --version=1.41.3`. It'd be great if I could run either `deno upgrade --version=1.41` or `deno upgrade --version=~1.41.0`, without having to first manually figure out which exact version I want.

This need would probably be more common once you release a new major version, since some projects might need Deno 1 to run and I'd want to install whatever the latest 1.x.y version was.
