Classic Block: Consider to make the editor keyboard shortcuts visible in the tooltips

[afercia]

In WordPress, https://core.trac.wordpress.org/changeset/38897 made some editor keyboard shortcuts more discoverable by adding them to the buttons tooltips. See also https://core.trac.wordpress.org/ticket/43773

Instead, in Gutenberg the keyboard shortcuts are not exposed in the tooltips, not even the ones in the Classic editor (which is TinyMCE):

For more details on how the shortcuts are added and translated, see src/wp-includes/js/tinymce/plugins/wordpress/plugin.js in WordPress, which gets the translations from PHP via the localized editor settings object.

Aside:
notice the positioning (and size) of the tooltips in the classic editor block (TinyMCE) is different from the one in the Gutenberg blocks.

Some shortcuts are now displayed in the tooltips, see #6605 and #6669. The classic block doesn't show them yet, though.

I'd say this should be solved, as it's important for accessibility and also because there's no feature parity with the Classic Editor. /Cc @azaozz @iseulde
