[BUGFIX] Accept JS spam protected email addresses

When TYPO3 is configured to spam protect email
addresses using an offset, then the HTML sanitizer
introduced in #94375 will remove the generated
JavaScript in the href link attribute.

This change makes the HTML sanitizer aware of the
`javascript:linkTo_UnCryptMailto` pattern for href
attribute.

Resolves: #94776
Releases: master, 11.3, 10.4, 9.5
