MySQL Crash dump on AlmaLinux

[Sophal Lee]

I have sent SIGABRT to MySQL process but I am not getting the crash dump file. Server is AlmaLinux 8.8 (4.18.0-477.21.1.el8_8.x86_64 x86_64 x86_64) and MySQL version is 8.0.32.

Set the configuration as follows and restarted to no avail:
```
[mysqld]
core-file

[mysqld_safe]
core-file-size=unlimited
```

Set the core to unlimited
```
$ cat /proc/`pidof -s mysqld`/limits|egrep '(Limit|core)'
Limit Soft Limit Hard Limit Units
Max core file size unlimited unlimited bytes
```

I tried setting these values as below but it is not accepted and result in MySQL failing to boot up.
```
[mysqld]
core-file
core-file-size=unlimited
core-file-path=/home/crash/apps/
```

I tried setting the core dumps in systemd and restarted MySQL. Issue is still there.
```
LimitCORE=infinity
```

It works with gcore but I want to test it when I send SIGABRT to MySQL. MySQL failed last time with SIGABRT and I want to test dump is working as expected.
