Use consistent decimal places in BeatmapAttributeText

[cloudrac3r]

Currently, BeatmapAttributeText will always display 2 decimal places, possibly with trailing zeroes, for attributes that normally don't have trailing zeroes.

In most of the game, and on web, difficulty attributes are displayed with one decimal place, but can be displayed as whole numbers if there are no decimals e.g. (CS 3.8, HP 5.5, Accuracy 9, AR 9.2) for https://osu.ppy.sh/beatmapsets/1314891#osu/2725039. If mods are applied, difficulty attributes will be displayed with up to 2 decimal places. This can be seen by turning on DT then looking at the top left section of lazer song select. So I have changed the difficulty attribute format to 0.##.

The same logic applies for BPM. Usually it's displayed as a whole number, but it can have up to 2 decimal places if necessary: https://osu.ppy.sh/beatmapsets/2268670#fruits/4831566. So I changed this format to 0.## as well.

I have not changed the display of star rating because it's always 2 decimal places with trailing zeroes: https://osu.ppy.sh/beatmapsets/2253429#osu/4794131

I tested this manually and it seems to work. I'm not sure if there's any automated tests that need to be updated.

Seems ok to me

Tests need adjustments here.

Have fixed the tests.

Two things to @cloudrac3r:

• I'll forgive making the commit on github.com this time, but for anything more serious, please don't.

• Either github tooling has potentially terminal breakage for whatever reason, or something somewhere with your git setup is borked. I initially couldn't push to this branch to fix the tests because of whatever this is:

  remote: Resolving deltas: 100% (14/14), completed with 10 local objects.
  To github.com:OpenSauce04/osu.git
   ! [remote rejected]       patch-1 -> patch-1 (permission denied)
  error: failed to push some refs to 'github.com:OpenSauce04/osu.git'
  

  I cloned the branch using github's own gh, so I dunno what is up with whatever that is. A manual edit in .git/config to point at the correct remote fixed this.

Username OpenSauce04 is not my account, so it's strange that you saw that error. I've taken your advice for next time. Thank you for fixing the tests!
