Fix tag being truncated when copying to clipboard (#4232)

Copy the whole tag to clipboard instead of truncating to the value of
TruncateCopiedCommitHashesTo.

- **PR Description**
My PR for copying the tag to clipboard was recently merged (#4219).
While using LazyGit built from the latest master I noticed that some
tags were being truncated, turns out it was due to a bug I introduced on
that previous PR.
Sorry for that.
