Resolve i18n warnings

[richard-cox]

Setup

• Rancher version: 2.7.5
• Rancher UI Extensions:
• Browser type & version:

Describe the bug

• When running ember / old ui it scans localisation files for fields missing in en-us
• There's quite a few of these
• We need to either remove them from the l18n file... or add them to en-us (probably the later)

I'm updating this to dev-validate since these errors only show up when running the ui locally.
