Please set default branch to 'main' in codecov.io

Describe the bug

Since we enabled the code coverage using Codecov Getting the error Please upload report for BASE (main@####).

To Reproduce

Just open a PR with any change:

Validate the issue
Click the Codecov badge or visit the site
This will use branch 'master', which is an old codecov result:

How to fix
A project administrator needs to visit https://app.codecov.io/gh/testcontainers/testcontainers-python/settings and change the default branch from 'master' to 'main'. It should look like this:

Follow-up on #544

I wanted to do it, but Codecov does not see the main branch for me:

Edit:
No clue what to do here, maybe re-adding Codecov so it has a refresh context?

[Tranquility2]

I think I found the root source, the upload fails when running on "main" (so it has no idea about this branch)
for example: https://github.com/testcontainers/testcontainers-python/actions/runs/10200870537/job/28221518487

Error: Codecov token not found. Please provide Codecov token with -t flag. Warning: Codecov: Failed to properly create commit: The process '/home/runner/work/_actions/codecov/codecov-action/v4/dist/codecov' failed with exit code 1

Codecov token not found

This is actually happening for all branches.. what I think is happening is that we don't have the token (or its not update to date in the secrets) so we do get some reports uploaded but its very partial (once every few runs)

We can try to Generate a new token, there is a guide:

tried pushing to master, ran into same issue with token not being found.
