[e2e] CouchDB notebook tags test is failing

[jvigliotta]

Summary

The error can be seen here: https://github.com/nasa/openmct/actions/runs/4010747788/jobs/6887596721

The issue seems to be that the "Add Tag" button has moved from the entry to the inspector. These tests just need to be updated.
I believe it's this line (and the same ones that follow):

openmct/e2e/tests/functional/plugins/notebook/notebookWithCouchDB.e2e.spec.js

Line 98 in 9c78439

await page.hover(`button:has-text("Add Tag")`);
