[Woo POS][App Listings] Update listing title and subtitle meta

[iamgabrielma]

Continuation of #16346
Closes WOOMOB-1641

Description

This PR updates name.txt and subtitle.txt that will be used in app store across all languages.

Changes:

• WooCommerce -> WooCommerce: Store Management & POS
• Your store in your pocket -> All-in-one mobile ecommerce

Test Steps

• Run bundle exec fastlane run configure_apply so that the ASC API key file is present in your machine.
• If they key cannot be found, you might need to copy it over cp fastlane/env/user.env.example ~/.wcios-env.default
• Run bundle exec fastlane update_metadata_on_app_store_connect
• Once the lane finishes, should automatically open a preview in your browser: file:///{your machine}/woocommerce-ios/fastlane/screenshots/screenshots.html
• When the systems prompts you with the following confirmation, answer no so it does not actually upload it to ASC.

[10:26:00]: Does the Preview on path './fastlane/Preview.html' look okay for you? (y/n)
n
[!] Did not upload the metadata, because the HTML file was rejected by the user

• Back in the HTML preview, scroll down to en-US and you should see the updated name and subtitle:
