Works around:

• TeachingTip is not read by Windows Accessibility Narrator when IsLightDismissEnabled=True microsoft-ui-xaml#9601

Detailed description of the pull request / Additional comments

I had to use a workaround to make the TeachingTip text readable:

• Change the text inside from a Subtitle to a Title (which bolded the text)
• Set IsLightDismissEnabled to false (which added the close button)

Although the workaround makes some minor cosmetic changes, I believe those are worth the additional functionality until the WinUI 3 TeachingTip is updated.

Change the text inside from a Subtitle to a Title (which bolded the text)
Why is this part of the work around?

When I had just IsLightDismissEnabled set to false, the Subtitle wasn't read:

I found that the Subtitles weren't narrated in the WinUI 3 Gallery as well. I'm not sure if that's by design. I mentioned this in the winui-xaml issue so their team is aware of it.
