fix(console): correct the parseCssColor algorithm (#19645)

This is a fix for issue #19644, concerning the `parseCssColor` function
in the file `ext/console/01_console.js`. Changes made on lines
2756-2758. To sum it up:

> The internal `parseCssColor` function currently parses 3/4-digit hex
colors incorrectly. For example, it parses the string `#FFFFFF` as
`[255, 255, 255]` (as expected), but returns `[240, 240, 240]` for
`#FFF`, when it should return the same triplet as the former.

While it's not going to cause a fatal runtime error, it did bug me
enough to fix it real quick.
