1912995 - Only show CSS variable value in variable tooltip (remove "--x = ")

Status: RESOLVED FIXED

(DevTools :: Inspector, task)

Description

[Nicolas Chevobbe [:nchevobbe]]

The tooltip already points to the variable name, repeating the variable name in the toolip doesn't add a lot of values (and that's something we do in the debugger for example)

Attachment: Bug 1912995 - [devtools] Don't repeat variable name in CSS variable tooltip. r=#devtools-reviewers.

This changes the --x = red tooltip content into just red.
We still keep the --x is not set as I'm unsure what the alternative could be
(and given it would probably still need localized string, as we can use unset,
which is an actual valid value)

Tests are updated to include the new tooltip content.
devtools/client/inspector/rules/test/browser_rules_preview-tooltips-sizes.js is
further tweaked to cover a frequent intermittent.
