[czaha-official]

Please confirm the following.

• I checked the existing issues for duplicate problems
• I have tried resolving the issue using the support portal

What browsers are you seeing the problem on?

Chrome (including Arc, Brave, Opera, Vivaldi)

Describe the bug

In the Japanese localization of the account settings page, there is a typo/inconsistency in the email section.

• Heading: "メールドレス" (Typo)
• Description underneath: "メールアドレス" (Correct)

Steps to reproduce

1. Log in to Modrinth.
2. Go to Account Settings.
3. Look at the email section, where the heading is displayed as "メールドレス".

Expected behavior

The heading should be correctly displayed as "メールアドレス" to match the description below and ensure consistency.
Also, I would like to know if it is welcome for me to continuously contribute to improving the Japanese localization moving forward.

Additional context

Also, I would love to continuously help improve and maintain the Japanese translation quality. If you are using Crowdin for localization, I would be even more glad to contribute there—please let me know the details or where I can join!
