docs: update readme from mariadb with port binding, tags, remove double spaces and informations

[felipementel]

This pull request includes updates to the mariadb documentation and configuration files to improve clarity and compatibility, as well as to specify versions for certain images.

Documentation improvements:

• mariadb/content.md: Added an important note about the %%IMAGE%% tags to highlight the latest and lts versions.
• mariadb/content.md: Updated the Docker compose command to use docker compose instead of docker-compose for consistency with the latest Docker CLI.
• mariadb/content.md: Added a section on port binding to explain how to expose the container port to the host port using the -p argument in the docker run command.

Configuration updates:

• mariadb/stack.yml: Specified the image versions for mariadb and adminer to ensure consistency and compatibility. The mariadb image is updated to 11.7-ubi and adminer to 4.17.1.
• mariadb/stack.yml: Remove docker compose version on file header - the docker compose version is obsolete

Do I need to make any further adjustments for analysis and approval?
