[ci skip]

Fixed suggestion in documentation resulting in linting error 'variables should be a map of key-valued strings'

Documentation now suggests a valid option with the intended result.

See #3147 

`"yes"`, opposed to `yes` is not casted to a boolean. `variables` only accepts key-valued strings.

Better solution would be to change the parsing of `variables` (allow boolean or check the actual value of the string).

It's not complete accurate to include the push command-line instructions, but users may still want the instructions to clone. After:

Animate the logo on hover

The logo is now rendered as pure SVG, rather than image referencing a
svg. The SVG has an id and the shapes of the logo have a shared class.
The shapes change their fill color on hover with a transition.

Identical to how it looks on about.gitlab.com
