Remove Bootstrap version reference from tooltip.scss

We've had some reports that Nextcloud is using an outdated/deprecated Bootstrap version v3.3.5.

I believe this to be caused by the string "Bootstrap v3.3.5" in the changed line, which after bundling ends up in `core-common.js`, and trips up some security scanners.

It may also be worth investigating why the comments are not getting stripped when bundling the JS.
