Improve hyperlinks rendering in tables

[L20L021902]

Description

This PR adds cma css class to a tag when table is rendered. It also removes href attribute from a tag and adds title attribute with links.

Changes

• Changes are done in table-editor.ts file. All a tags selected then loop through the tags. If a tag does not contain cma class then add the class to it.
• The link-tooltips.ts search cma class and title to add tooltip on mouse hover. So, href removed and title added to a tags.

	// Only for links with cma-class
	if (a.tagName !== 'A' || !a.classList.contains('cma')) {

	// If there's already a tippy on the instance, don't re-render it
	if ('_tippy' in a) {
	return
	}
	// Retrieve the link target
	const linkTarget = a.getAttribute('title')

Thank you for opening your first PR! 🎉 We are very happy and would like to thank you very much for your contribution. If everything checks out, we'll make sure to review the PR as soon as possible and give feedback. In the meantime, to make the reviewing process as fast as possible, you can help us by checking the following things:

• Did you follow the JSStandard coding style? - Did you comment everywhere where the necessity of a piece of code or the
  way it was implemented is not immediately obvious?
• Did you attempt to stick as much to current coding habits as possible?
  (Note that this does not apply to pieces of code where we ourselves
  obviously violated good coding practices, which unfortunately happens
  sometimes. But please indicate this in your PR so that we know what you
  rectified!)

Furthermore, make sure that the linter does not complain, which will check your code on every new commit. If the linter task fails, make sure to run yarn lint locally and check the file eslint_report.htm which will tell you precisely what went wrong.
Stay sharp, and thanks again!

In general a good idea, but it would be great if you could check my suggestion if that works as well, as it's then less prone to break.
