fix(files_external): Remove invalid jQuery Tooltip usage

[susnux]

• Resolves: [Bug]: Impossible to add an external storage in 29 #44204

Summary

The tooltip methods were remove long ago but we removed the "polyfill" (try-catch) so this caused the UI to throw an error causing it to be unusable.

And what about those:

> grep '.tooltip(' -R core
core/src/systemtags/systemtagsinputfield.js:                            $renameForm.find('[title]').tooltip({
core/src/systemtags/systemtagsinputfield.js:                            $(ev.target).tooltip('option', 'hide')
core/src/systemtags/systemtagsinputfield.js:                            this.$el.find('[title]').tooltip({ placement: 'bottom' })
core/js/backgroundjobs.js:      $('.section .icon-info').tooltip({

UI is working again with this PR.
Only problem I’ve spotted: clicking the 3-dot button opens a menu, but clicking it again does not close it, the user have to find a spot in the UI that does nothing and click it, it’s the only way to close this menu.

/backport to stable28

Actually not sure if 28 is impacted or not, @susnux ?

tested and seems to work :)

No stable 28 was not affected, we only did this for 29 iirc.

And what about those:

Unrelated, those should not cause problems. The 3-dot menu is another issue. I hope to find time to migrate the settings to vue soon 😉
