[MC-279159] The "options.framerate" string is improperly capitalized

For a bit of context, an acronym is an abbreviation formed from the initial letters of other words and pronounced as a word, for example, "ASCII" and "NASA". Within the English language, acronyms are usually written in capital letters and since "FPS" is an acronym, it should be capitalized.

Affected String:
