Changing the error message when file not scanned.

[rohitpatilok]

Closes #8051

I have addressed the issue where the error message lacked proper spacing before the closing tag. The problem was with the strong tag not having a space before closing, which resulted in the incorrect formatting of the error message.

I have added the space before the closing strong tag, and now the message is displayed as expected:

     Error while scanning for resources to import: File is required

Please review the change, and let me know if further adjustments are needed.

Thanks!
