Fix: Question mark and color Login.gov sizing alignment

[machikoyasuda]

fixes #1553

This PR only deals with the color Login.gov icon (on Elig Index and Enrollment Success), and the question mark next to the Login.gov icon on Elig Index

The issues:

• Sizing - ? should be 22x22, on both Desktop and Mobile
• Sizing - the color Login.gov is a bit smaller than the white one, at 120x16.
• There doesn't need to be the margin of 2px between the Login.gov button and the question mark (and any text).
