Use Tag instead of Version in goreleaser config

[awilmore]

Hi @lwolf , this is just a small change, but we are hoping the next image, v0.8.5, will be created as a cross-platform image (the current v0.8.4 image seems to be x86 only).

Can you explain how this change supposed to fix the issue?

There is no issue with the goreleaser config as it is. This PR just switches to using {{ .Tag }} instead of v{{ .Version }}.

The actual issue is that when the v0.8.4 tag was created, a cross-compiled 0.8.4 image was released by the Github action. But somehow a v0.8.4 image was also released, which is actually just a retagged version of the 0.8.4-amd64 image:

So this PR is a very minor change, and it is more about the next release, v0.8.5, which should hopefully show up in quay.io as a normal manifest wrapping the amd64 and arm64 images.

I manually retagged 0.8.4 into v0.8.4 before adding this change 538f00d
I believe next tag should be good anyway.

@lwolf if this is okay to merge and tag, we will be able to see if the next release is cross-compiled correctly.
