Update for WCAG 2.2 compliance

[WesleyBranton]

In an effort to make the content of the internet more accessible to everyone, all of my repositories will be reviewed to ensure that they fulfil the WCAG 2.2 requirements. This will take time. The current goal is to make all projects comply with level AA, including as many level AAA standards as possible.

Items that are bold are new to WCAG 2.2. Items that do not apply to the project will be marked as completed and marked with a strikethrough.
