fix: adds labels for multiple selected artifacts

[antoine29]

Thank you for contributing to Harbor!

Comprehensive Summary of your change

When selecting multiple artifacts and adding a label for these, only the first selected artifact gets labeled. Current frontend code is adding the label only to the first selected artifact. This PR is fixing this by iterating the array and adding the label to each selected artifact.

@antoine29 Thanks for submitting the PR.
I don't have UI expertise so can't really comment on the code...
Could you explain how the errors are handled if the requests partially failed, i.e. some artifacts are labeled successfully but some failed?

The refresh() method will be called when the first callback is called, this is not expected.
We should call the refresh() method only when all requests are completed.
Maybe 'forkJoin' function can match our requirements.

this.selectedRow will be reset to empty array when the refresh() method is called.
this.selectedRow = []

if all the iteration is not done after the first request get completed, it will call the refresh() to reset the
this.selectedRow = []
Add/Remove labels will not be triggered for the items that not iterated before the selectedRow was reset to []

@xuelichao thanks for the feedback. I'll look at the 'forkjoin' operator.
