Incorrect documentation of `my.cnf` Path for MySQL Image with Oracle Linux

[tantee]

It appears that there has been a change in the file path for my.cnf in the MySQL Docker image using Oracle Linux. The configuration file my.cnf is now located at /etc/my.cnf instead of the previously documented path /etc/mysql/my.cnf.

Steps to Reproduce:

1. Pull the latest MySQL Docker image based on Oracle Linux.
2. Run the container.
3. Check the location of the my.cnf file.

Expected Behavior:

• The my.cnf file should be located at /etc/mysql/my.cnf as per the current documentation.

Actual Behavior:

• The my.cnf file is located at /etc/my.cnf.

Suggested Fix:
Please update the documentation to reflect the new file path (/etc/my.cnf) for the MySQL configuration file in the Docker image using Oracle Linux.

Ah good catch -- https://github.com/docker-library/docs/blob/03cc5a4427fb577f1e52114a21ed7e31905ad319/mysql/content.md?plain=1#L59 is where this documentation lives.
