Add scape char to percentage symbol

[andres-blanco]

Closes DOTCON-45

Proposed Changes

Scape the percentage symbol so it's correctly ignored when interpolating. This should be merged once all the translations are ready and the string displays correctly in all languages.

Why are these changes being made?

On languages different than English this string is producing an unexpected translation.

Current translation looks like:

Since the % is a reserved character for interpolation, we need to scape it so it's dealt with correctly when translating.

Testing Instructions

NOTE: this will only work when the translation for the new string with the scaped % exists

• Change your account to a language different that English
• Open the calypso.live link below and navigate to /setup/site-migration/site-migration-how-to-migrate
• Verify the percentage symbol is displayed correctly
