fix(exporter-logs-otlp-http): add @opentelemetry/api-logs as dependency

[pichlermarc]

Which problem is this PR solving?

The docs workflow is failing as the dependency to @opentelemetry/api is missing (edit: fixed in the meantime by #4020). This PR adds @opentelemetry/api as a peer and dev dependency. @opentelemetry/api-logs was listed as a peer dependency. As @opentelemetry/api-logs is still experimental, this PR moves it to dependencies.

@opentelemetry/api being missing is likely not a problem when using the exporter, as it is included in other dependencies. However, it should be listed as a peer dependency regardless.
