Fix/INV-707/Missing tooltip

[jsconan]

Related to: https://oat-sa.atlassian.net/browse/INV-707

Requires:

• Fix/INV-707/Missing tooltip extension-tao-itemqti#2414 (needed for future compilations)

Summary

Restore the tooltip helper in the textReader PCI.

Also:

• make sure it works with TAO Advance.
• fix the tooltip not showing up in the item authoring preview (needs the companion PR)

Details

When migrating the PCI to the IMS standard, we made some surgery to remove or adapt incompatible code. However, it was a tad too aggressive, and the helper responsible for preparing the tooltip was removed together with the one that brought MathJAX.

How to test

• install TAO with the extension pciSamples
• check out the branch
• have an item with the textReader PCI and some tooltips (you can use the ones attached to the ticket)
• check that the tooltip is visible in the preview
• publish a delivery (or pick up an existing one if any)
• take the test and check the tooltip works

Only code check. I wanted to install locally, but I have issue with my stack.
