[DialogHeader] Allow dialog title exclusion from tab index

Pull Request

📖 Description

No possibility to exclude the dialog title from the tab index. The FluentDialogHeader provides a default tabindex of 0 which could not be overwritten.
Repro:

Now it is possible to adjust the tabindex by means of the new parameter TabIndex. In case you also do not wish to not see the dismiss tooltip, you can set the new parameter ShowDismissTooltip to "false".

This tabindex=“0" attribute is present to avoid displaying the ’Close” tooltip when the dialog box is open. You can see this in your second example.

@NataschaZorgWijnhoven I'm seeing build errors in the pipelines (not finding CssBuilder/StyleBuilder). Can you check locally and correct?

The build errors have now been fixed.

@NataschaZorgWijnhoven just one more request...can you update the PR description to the latest state of what has actually been done (ie no more ExcludeFromTabFocus but now ShowDismissTooltip and TabIndex).

Build here on GH has indeed concluded successfully now so updating the description is the last thing before we can merge

Good call. I have adjusted it to reflect the current implementation.
