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:
[x] take over search adjustments from [[ https://gerrit.wikimedia.org/r/c/mediawiki/extensions/VisualEditor/+/667641 | 667641 ]]
[x] adapt variables according to [[ https://gerrit.wikimedia.org/r/c/mediawiki/extensions/VisualEditor/+/686436 | 686436 ]]
[x] create a new config variable for this extension (e.g. TemplateWizardTemplateSearchImprovements)
[] add * to template search term like in [[ https://gerrit.wikimedia.org/r/c/mediawiki/extensions/VisualEditor/+/689070 | 689070 ]]
[] add the "exact match" feature in a separate patch, just as in [[ https://gerrit.wikimedia.org/r/c/mediawiki/extensions/VisualEditor/+/693157 | 693157 ]]
[] add tests (like in [[ https://gerrit.wikimedia.org/r/c/mediawiki/extensions/VisualEditor/+/667641 | 667641 ]] )
