fix(steamcmd): add libtinfo.so.5 symlink fix for readline warning

On distros shipping libtinfo.so.6 but not libtinfo.so.5 (Ubuntu 22.04+,
Debian 12+), SteamCMD prints:

  WARNING: Failed to load 32-bit libtinfo.so.5 or libncurses.so.5.
  Please install (lib32tinfo5 / ncurses-libs.i686 / equivalent) to
  enable readline.

lib32tinfo5 does not exist on Ubuntu 24.04. Creating a user-space
symlink inside the steamcmd directory resolves the warning without
requiring root or a missing package.
