FCM: Unquote padding-bottom value in video-playing class

[anselmbradford]

This value was invalid if it was quoted, so this unquotes it.

Changes

• FCM: Unquote padding-bottom value in video-playing class

Testing

1. This shows up on FCM videos, such as on https://www.consumerfinance.gov/consumer-tools/reverse-mortgages/, where if the value was quoted the video play area would be squashed to zero pixels.
