[component] make Type implement MarshalText

[TylerHelmuth]

Description:
Adds MarshalYAML function so that Type can be properly marshaled as yaml.

We could alternatively fix this issue by updating the components command to explicitly call Type.String and use that value instead of component.Type in its struct.

Link to tracking Issue:
Fixes #9855

Testing:
Tested locally using otelcorecol. The unit test TestNewBuildSubCommand didnt catch the issue because it was also using yaml.Marshal like the command, so the expected value also had {} as the name.

Also, the test for this functionality is pretty useless. It'd be great to update it to compare the expected output with an actual yaml string instead of doing the same marshaling. Could you please update it?

I believe the windows test failure is unrelated
