Not possible to add "Name" field and save forms while using user language "German"

[steve-p96]

Describe the bug

I encountered a strange bug related to the language setting of the user account in the Craft CMS control panel. When the user language is set to "German," adding a "Name" field to a form and then attempting to save the form triggers an error.

Steps to reproduce

1. Set the user language to German in the Craft CMS control panel.
2. Create or edit a form.
3. Add a "Name" field to the form.
4. Attempt to save the form.

Form settings

• Multi-page form: No
• Submission Method: Page Reload
• Client-side Validation: No
• Custom Form Templates: No

Craft CMS version

5.4.6

Plugin version

3.0.7

Multi-site?

Yes

Additional context

• This issue only occurs when the user language is set to German.
• I have tested the same steps with English, French, and Spanish languages, and the form saves correctly without any errors.

Should be fixed for the next release. To get this early, run composer require verbb/formie:"dev-craft-5 as 3.0.9".

Fixed in 3.0.10
