Same as T274903, but for the #mediawiki-extensions-templatewizard.
[] Implement behind feature flag with:
* {T271802}
* {T274903}
* {T274906}
* {T274908}
Note this would need a separate feature flag in case we want to hide it.
Implementation:
* take over search adjustments from https://gerrit.wikimedia.org/r/c/mediawiki/extensions/VisualEditor/+/667641 but create a new config variable for this extension (e.g. TemplateWizardTemplateSearchImprovements)
* adapt variables according to https://gerrit.wikimedia.org/r/c/mediawiki/extensions/VisualEditor/+/686436
* add * to template search term like in https://gerrit.wikimedia.org/r/c/mediawiki/extensions/VisualEditor/+/689070
* add the "exact match" feature in a separate patch, just as in https://gerrit.wikimedia.org/r/c/mediawiki/extensions/VisualEditor/+/693157
