V16: Stylesheet Create Options

[leekelleher]

Description

Following on from the removal of RTE Stylesheets #18908, we need a way for a 3rd-party TinyMCE package can re-introduce RTE Stylesheets, we needed the Stylesheet Create menu to be powered by entityCreateOptionAction extensions.

This PR deprecates the "Stylesheet Create Options modal" (which had hardcoded options; for removal in v18), replacing it with the extensible entityCreateOptionAction options.

• Creation of a new UmbStylesheetCreateOptionAction for constructing stylesheet creation URLs.
• Deprecation of modal-related types and elements in favor of extension-based actions.
• Updates to manifests to register the new entity actions and mark legacy modal components as deprecated.

• Consider verifying the use of the string 'null' as a fallback for this.args.unique. Confirm that this behavior meets the intended URL structure when the unique identifier is missing.

const href = `section/settings/workspace/stylesheet/create/parent/${this.args.entityType}/${this.args.unique || 'null'}`;
