Login failed message translation to Hungarian language is incorrect

Issue Summary

Login failed message translation to the Hungarian language is incorrect 

Steps to Reproduce

1. Navigate to Jira administration > System > Global configuration 
2. Update the Indexing language and Default language to Hungarian under Internationalization.
3. Also, change the profile language to Hungarian
4. Now try to logout and login with incorrect credentials

We tested in both 8.20.11 and also 9.7 however the same behaviour is observed.

Expected Results

The message should be displayed like the below:

A felhasználónév és jelszó érvénytelen - próbálja újra.

As this "érvénytelen" is the correct Hungarian word

Actual Results

The below message is being displayed however there's no such word in Hungarian like this érévnytelen

A felhasználónév és jelszó érévnytelen - próbálja újra. 

Workaround

As the language pack i.e jira-core-language-pack-hu_HU-8.15.0.20211201009999.jar file has incorrect wording like \u00e9r\u00e9vnytelen and that should be changed to  \u00e9rv\u00e9nytelen in the JiraWebActionSupport_hu_HU.properties
