[2025-TF2-SDK Update] [Linux-only] Workaround current Linux broken filename casing issue

[nullsystem]

Build Info

20250222 (2025-TF2-SDK branch)

Description

This is a Linux-only and upstream issue, any fonts that have upper cases EX: In NT: NEUROPOL2.ttf will not be picked up and instead fallback to some fallback font.

This is a known issue in TF2 and upstream SDK: ValveSoftware/Source-1-Games#7020

There is a workaround though, rename NEUROPOL2.ttf to neuropol2.ttf and point to the lowercase version and Linux build will pick it up again. Source: ValveSoftware/Source-1-Games#7020 (comment)

Only filing it on wether to do the workaround and distribute a lowercase named TTF files.

To Reproduce

1. Use Linux new 64-bits 2025-TF2-update build
2. Look at where neuropol2 and xfiles would be used, and see that the default is used instead

Expected behavior

Neuropol2, xfiles, etc... are picked up and used

Actual behavior

Neuropol2, xfiles, etc... are not picked up and used, and instead the default fallback HL2 font
