Safari NumberFormat error fix.

[revanth0212]

Description

Safari browser has a bug related to the INTL NumberFormat polyfill. We are already handling it in the code but unfortunately, we are throwing an error as well. Since an error is thrown the whole app crashes on Safari instead of rendering the app with the handled logic.

This PR simply changes the function to not throw and warn instead to let the backup logic do its magic and render the app.

QA

📝 Tested on using Safari Version 14.1.2 (14611.3.10.1.5) on macOS Mojave 10.14.6.

To Do

✅ Passed

• Test Plan
• MFTF
• Lighthouse
• Alternate Browsers

🚫 Failed

• Cypress

PageBuilder button and image tests kept failing but this change had nothing to do with them. The backend is quite slow currently so I am merging even though I haven't actually witnessed these tests pass.
