Set Minimum Character Limit for Title Field

Description:

Currently, the corpus collector app at corpus.swecha.org allows users to upload files with a Title field that has no minimum character limit. To ensure that titles are descriptive and meaningful, it is proposed that the Title field should have a minimum requirement of 8 characters.

Tasks:

• Update the frontend to enforce a minimum character limit for the Title field.
• Implement validation to ensure the Title field has at least 8 characters.
• Update the backend to handle the new validation rules.
• Provide appropriate user feedback when the Title field does not meet the requirements.

Additional Notes:

• Ensure that the user interface clearly indicates the new requirements for the Title field.
• Update any relevant documentation to reflect this change.
