Odd font for Celsius and Fahrenheit with Win10 + Chrome

[Nancy-Salpepi]

For phetsims/qa#970, the font for Celsius and Fahrenheit is different than Kelvin in Win + chrome.
I don't see this with mac + chrome/safari or win + FF.

Win10 + Chrome:

I believe this is due to the fact that I'm using single unicode characters for "degrees Celsius" and "degrees Fahrenheit". I could change this to be two separate characters, since I just checked and there is a separate character for degrees. It may not look quite as compact, but will be more consistent.

I went ahead and changed this on the main branch, and I can see the difference on my machine. Below are some screenshots.

I just reviewed this with @arouinfar over Zoom, and she and I agree that this seems like an improvement. I'll need to change it in the previously submitted translation files too.

This has been fixed for all existing translations as of this moment.

• Note to self: Check for single-char versions of these units in translations just before publishing, since some could sneak in between now and then.

Things looked good on Win 11 Chrome and Firefox. Will reopen if anything shows up in other platforms.
