Feedback

While trying to configure TLS in otelcol.exporter.otlp, I found out that the documented min_version = "TLS 1.2" does not work:

level=error msg="failed to start scheduled component" component_path=/ component_id=otelcol.exporter.otlp.ops err="failed to load TLS config: invalid TLS min_version: unsupported TLS version: \"TLS 1.2\""

Using trial-and-error I found that the correct format is min_version = "1.2".

On the other hand in docs/sources/shared/reference/components/tls-config-block.md the format is documented as min_version = "TLS12".

I think that the TLS version should be formatted consistently among all the components and also properly documented given that this is a security feature.
