Add version to release file name

[JonasScharpf]

Thank you for bazelisk!

While doing automated updates of bazel is quite easy, it's more difficult with bazelisk. Mainly due to the missing version information of the downloaded bazelisk binary.

I would request to add the version to the bazelisk file name e.g. bazelisk-v1.20.0-linux-amd64 for the release files like it's done in Bazel (e.g. bazel-7.3.1-darwin-x86_64 )

This relates to #483
