Accessibility Amends for the Content Info Tab

[RachBreeze]

As a result of investigating #8704 I have added an alias for the content info tab to ensure that the template drop down is labelled correctly.

I have also added a space on the open buttons to ensure that the copy reads better than shown below.

Finally I have removed the title attributes on the links in umb-node-preview as they held duplicate (but unlocalised) content as the link text and could result in some screen reader users hearing duplicate messages.

• The automated tests all pass (see "Checks" tab on this PR)
• The level of security for this contribution is the same or improved

@RachBreeze @nul800sebastiaan I noticed at least one reference here, where <localize /> directive was self-closing. It is a custom HTML element, so it should have a end-closing tag similar to web component.

<localize></localize>

Self-closing elements are valid for a limited set og HTML elements like input, br, img etc.
