Remove the use of accesskey

[xuhdev]

What does this PR change? What problem does it solve?

accesskey is quite problematic. MDN advises not using accesskeys for general purpose websites for various reasons: https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/accesskey#accessibility_concerns

WebAIM also recommends against using accesskeys generally: https://webaim.org/techniques/keyboard/accesskey

Was the change discussed in an issue or in the Discussions before?

No.

It will stay until browsers remove the support

[xuhdev]

I don't think browsers will ever drop support because access keys are useful in some cases. The PR description says they are not recommended to be used in a general website, citing various sources.
