Stay compliant with accessibility scorecard after a11y grading.

[agniuks]

To stay compliant (grade C) with the Accessibility Scorecard, we'll want to fix Sev 1 and Sev 2 bugs within 60 days of the creation date (by August 20th). Up to 5 Sev2 bugs can be fixed within 120 days instead of 60 and still be considered "in SLA."

Sev 1

• Wrapped Windows Control and Community Module "stickers" are truncated. #237
• Combo boxes text is truncated in Picker button. #236
• After expanding, text inside the button is truncated in Expander button.  #235
• Date is truncated in Date picker. #234
• Narrator is not announcing name of the button, while navigating in the left navigation pane. #226

Sev 2

• Keyboard focus is not visible on the elements while navigating with tab key. #222
• Tooltip is not defined to expand/collapse button in left navigation pane. #223
• In Permissions, after invoking ‘Request’ button, keyboard focus is falling on ‘Source code’ link. #224
• Screen Reader is not announcing the exact state of expand/collapse button in navigation pane.  #227
• A11y issues due to gallery not responding to high contrast theme changes #232
• In Button page, The Name is included with the same text as the LocalizedControlType. #233
• Color is solely used to identify the links as a link in Settings page. #238

Then to close out the linked ADO issues:

• Release a new version of gallery, which includes these fixes (or send a build for testing)

Fix for issue #222 still needs to be merged in here, but it's been updated in the store and confirmed as resolved by the testing team. Going forward, we'll have Gallery tested with each release and have to address any issues if they come up, but for now we're in the clear 🎉
