Install screens: “Log In” and "Support link" use old color

[huzaifaalmesbah]

In the WordPress install flow, links such as “Read the support article on wp-config.php” and “Log In” are using the outdated link color instead of the updated admin color.

Thanks for the PR, this looks good to me 👍

Thanks for the PR, this is ready to ship.

I'm separating this in two commits, as the two patches are fixing the issue in very different locations and with a different implementation.

[audrasjb]

Wait, @hbhalodia are you sure these are the correct colors?
By the way we'll also want to update :focus colors and the other related styles (like the border/border-radius of the outline).

Removing commit for now.

[audrasjb]

As per today's bug scrub:
I'm not 100% sure the proposed PR uses the good color values. I pinged the PR author but another check is welcome.
Invoking @wildworks or @sabernardt, just in case you can help to confirm the issue or not?

I tested the changes locally using the provided updated code, and the updated link colors look consistent with the new admin design system. The “Log In” and support article links now match other admin link styles.

From my testing, the color values appear correct and align well with the intended UI refresh. Overall, the update looks good to me.

​PR 11373 needs to be updated. The correct color is not being used in some parts of the code. Please refer to ​this discussion.
