Can't input a space in Form's submit button

[HardeepAsrani]

Description

It looks like you can't add a space directly in the Submit button of the Form block. You can only add it by copy/pasting it as typing a space is stripping it away.

Step-by-step reproduction instructions

1. Add a form block.
2. Try to modify the submit message with something like "Send Now"
3. You will notice the space isn't inputted.

@HardeepAsrani I've reviewed it and found that the issue appears to be with multiline={false}. If we set it to {true}, it also allows typing whitespace.

This issue might have started from here.

Do you have any suggestions on how to fix this issue?

Thanks

@girishpanchal30 RichText's behavior has changed with time, and you can review the props to see which one work the best to disallow line breaks but allow white spaces: https://github.com/WordPress/gutenberg/blob/trunk/packages/block-editor/src/components/rich-text/index.js#L80
