[Bug]: integer expression expected in script in rustserver

### User story

As a server admin, I'd like this resolved so I know theres no issues when executing rust server scripts

### Game

Rust

### Linux distro

Other

### Command

command: stop, command: restart, command: details

### Further information

[pvehard@games ~]$ ./rustserver details
/home/pvehard/lgsm/modules/info_distro.sh: line 100: [: : integer expression expected

Im running on AlmaLinux ver 8.9.

I added some debugging to the script to narrow down the problem. It seems line 100 gets called twice. The 1st time it's empty (this seems to cause the error) and the 2nd time it contains 8.9

my os-release file is in the log output section

This error seems to have been occuring for a few months now. It appears to not be causing a problem, but I can't be sure.

### Relevant log output

```shell
[rustserver@games ~]$ cat /etc/os-release
