What does this PR do?

Enables SSL for postgres

The main thing to recognize when reviewing this is that the secret material must be owned by the postgres user.
The docker file copy api doesn't allowfor setting a user when copying. The only way I could think was to take wrap the entrypoint script with one that does what we want.

Why is it important?

User ran into issue trying to use SSL. It's not obviously supported (able) due to file permissions.

We are in the right track with this one, although I left some comments that need to be addressed.

Besides that, we need to include the new option in the docs. Please check the docs/modules/postgres.md file for that. Remember adding this right after the option title:

- Not available until the next release of testcontainers-go <a href="https://github.com/testcontainers/testcontainers-go"><span class="tc-version">:material-tag: main</span></a>

Thanks!

@bearrito could you please take a look at #2478? I'm adding helper code to deal with TLS certificates in order to simplify the story for the client code. Wdyt?

@mdelapenya That makes a lot of sense. Much cleaner.

Do you want me to wait until that's done then base this on top of that?

@bearrito I went ahead and extracted the TLS cert generation to a separate go package, which makes more sense: https://github.com/mdelapenya/tlscert

Please take a look and use it as you need here!

Just one final concern regarding the entrypoint: do you think we need to pass it? Or is it something we can internally handle in the module, being transparent to the end users?

@mdelapenya Update so that the entrypoint is coupled with the ssl settings. What about doing something similar for the conf file?

I left a few more comments, sorry if that's taking too long 😞 My only concern is about the default SSL conf file, please see my comments about it.
