x/crypto: missing git tags with proper version semantics (vX.X.X)

[bardia-key]

What version of Go are you using (go version)?

$ go version
go version 1.16.4 linux/amd64

Does this issue reproduce with the latest release?

Yes

What operating system and processor architecture are you using (go env)?

go env Output

What did you do?

Using the golang.org/x/crypto pkg and noticed that it doesn't use the standard Go Modules versioning. Ie, the repository does not have any git tags.

What did you expect to see?

Proper git tags (vX.X.X) on golang.org/x/crypto so one can easily identify which version of the pkg they are using.

What did you see instead?

golang.org/x/crypto was updated to have a go.mod file but never went the full path of adding git tags with proper version semantics.
