ci(coverage): exclude examples directory from coverage

[a-kenji]

Closes: #372

Alternative: Use cargo make also in bacon, that way updates need to be only made in the Makefile.toml

I thought this would probably be via https://docs.codecov.com/docs/ignoring-paths rather than tweaking the lcov output. Not 100% sure though as I haven't looked deeply. Do you have any guidance on that?

[orhun]

Yeah, this should be done via ignore directive in codecov.yml

I wasn't sure about the change.

This:

Since Codecov works by ingesting your coverage reports from the testing tools, the key component needed for the integration is the ability to upload a coverage report (ideally from your CI provider) to Codecov.

Lead me to believe if we exclude the directory from the report itself, it wouldn't be ingested. But that doesn't seem what is happening.

I'll add a configuration file.
