x/website: footer text is cut off on smaller viewports

[komuw]

What did you do?

• go to https://golang.org/ on mobile

What did you expect to see?

• everything well laid out

What did you see instead?

• the letter 'R' in 'Report a website issue' is missing
• there's no space before the google logo

• my phone is iphone SE
• browser; chrome

Added NeedsFix but it's unclear what fixed means (perhaps changing the text to be "Report issue" is enough).
