Inconsistent capitalization for "fps"

When the game has to display framerates, it's usually followed or preceded by a text saying fps (frames per second).

This text was originally uppercase (FPS) everywhere, but was then made lowercase (fps) in the F3 debug menu. This is supposedly the intended spelling, as FPS is usually referred to first-person shooters and as units are usually lowercase, unless when there's a specific reason to have them capitalized (such as N for Newton or W for Watt).

Snapshot 24w33a recently added another inconsistency (options.inactivityFpsLimit), that was earlier only limited to the telemetry element.

• Red text means wrong spelling

• Green text means correct spelling
