Fix Rancher Prime logo for dark mode

[nwmac]

Summary

Fixes #15980

Occurred changes and/or fixed issues

Replace the incorrect svg with the correct one.

Note, we have the logo in another location for the about page for Rancher Prime. This PR does not change that (de-deup), but simply ensures the dark mode logo is the correct one.

Technical notes summary

Logo change

Areas or cases that should be tested

Switch brand to suse and verify that the logo in dark mode shows the geeko as green (not white).
