Don't rename these files! [According to Expo](https://docs.expo.dev/develop/user-interface/fonts/#how-to-determine-which-font-family-name-to-use):

> If you provide fonts as an array of file paths (as described above), on Android, the file name (without the extension) becomes the font family name. On iOS, the font family name is read from the font file itself. We recommend naming the font file same as its PostScript name so the font family name is consistent on both platforms.
