This Pull Request is now available for translation here: https://translate.wordpress.com/deliverables/17057736

Some locales (Hebrew, Japanese) have been temporarily machine-translated due to translator availability. All other translations are usually ready within a few days. Untranslated and machine-translated strings will be sent for translation next Monday and are expected to be completed by the following Friday.

Hi @arthur791004, could you please edit the description of this PR and add a screenshot for our translators? Ideally it'd include all of the following strings:

• No themes matched.
• Best matching themes

Thank you in advance!
