Change links to Handling Author Errors section to be on relevant attributes

[jnurthen]

The table at https://w3c.github.io/core-aam/#not_mapped includes the following incorrect information:

Handling Author Errors for States and Properties is referenced from the following attributes:

• aria-valuemax
• aria-valuemin
• aria-valuetext
• aria-valuenow (this one is correct)

It should be referenced from the following attributes:

• aria-checked
• aria-controls
• aria-expanded
• aria-level
• aria-valuenow

Note - I'm unsure what we should do about the implicit values for roles section (for example alert setting aria-live and aria-atomic) as this seems to be missing in core-aam unless I am not seeing it.
