[BUG] preciseRefreshRate value ignored when using custom format

[mathgeniuszach]

General description of bug:

• What happened: When using a type "display" module and setting a custom format including {3} (refresh rate), the refresh rate is printed with full precision while preciseRefreshRate is set to false.
• What should happen: The refresh rate should take into account preciseRefreshRate and round to the nearest integer like normal even when a custom format is set.
• Fastfetch version used: 2.20.0
• Did it work in an older version: no
• Where did you get the binary: installed via NixOS
• Does this issue still occur in the latest dev build? Afaik yes, because the issue is with this line, which takes the refresh rate value directly and passes it into a formatter:

  fastfetch/src/modules/display/display.c

  Line 146 in 788cad3

  {FF_FORMAT_ARG_TYPE_DOUBLE, &result->refreshRate, "refresh-rate"},

I suppose this wouldn't really be an issue if it were possible to specify the decimal place precision in the format directly, but fastfetch -h format only provides options for truncating strings, which isn't practical as the whole number parts of refresh rates can be 2 or 3 digits long. I've tried a few other format codes I know from other languages but they have not worked.
