- `vertical-collection` component was throwing errors during render when the tags list was filtered down causing slowdowns or full Admin crashes
- similar regression had popped up before and fixed in https://github.com/TryGhost/Ghost/pull/15207 but the dependency had been bumped again without realising it caused an error
- added a test that triggers the error-throwing behaviour in the tags input to help catch this in future dependency updates

This commit adds a test to the serialize method of `post-emaiserializer`. It checks whether the generated email HTML is valid and standard HTML5 and that all properties are escaped.
To do this validation, I depend on the new `html-validate` dev dependency. Just parsing the HTML with a HTML parser is not enough to guarantee that the HTML is okay.
Apart from that this fixes:
- Removed the sanitizeHTML method and replaced it with normal HTML escaping. We don't want to allow any HTML in the escaped fields. Whereas `sanitizeHTML` still allows valid HTML, but we don't want that and want the same behaviour as on the site. E.g., a post with a title `All your need to know about the <br /> tag` should actually render the same title and non-html content, being `All your need to know about the <br /> tag`
- The file, nft and audio card didn't (always) escape the injected HTML fields (new version @tryghost/kg-default-cards)
- `@tryghost/string` is bumped because it contains the new escapeHtml method

- resolves some deprecations raised by the addon which has fallen out of regular maintenance
- we were largely overriding much of the addon so the additional code was minimal, most of the changes were from updating to modern patterns

- use of the helper was generating deprecation warnings when building Admin
- removed the single usage in favor of using `{{perform}}` directly on a controller task property as there was no need to go via the route
- changed naming of task properties to include a `...Task` suffix so it's clear when dealing with a task object
