 KSES: Allow leading trailing double hyphen in data attributes

 Expand allowable set of custom data attribute names to include those
 containing
 leading, trailing, and double `-` characters. Previously, WordPress was
 removing data attributes that are used in the Interactivity API. By
 allowing
 these additional custom data attributes, the related Interactivity API
 directives will preserve through `kses`.

 For example, the Interactivity API frequently relies on custom data
 attributes
 such as `data-wp-on--click="..."`. The change in [43981] would strip these
 out
 of the processed HTML, however.
