Error messages from otel builder inappropriately quoted/escaped

[mattsains]

Describe the bug
When the custom collector builder fails, its error message includes an underlying error which usually is the actual content of the error. For example:

2022-11-21T09:56:12.767-0800    INFO    internal/command.go:125 OpenTelemetry Collector Builder {"version": "dev", "date": "unknown"}

As you can see, the error is quoted and escaped, so it's very difficult to read.

I plan to fix this myself soon because it's quite easy, but I need to write it down because I'm working on something else first.

Steps to reproduce
An easy way to reproduce this problem is to create a manifest yaml that describes an unresoveable dependency. For example, include a replace directive that can't be evaluated.

What did you expect to see?
The error message should be formatted as intended. In the example above:

2022-11-21T09:56:12.767-0800    INFO    internal/command.go:125 OpenTelemetry Collector Builder {"version": "dev", "date": "unknown"}

2022-11-21T09:56:12.771-0800    INFO    builder/config.go:107   Using go        {"go-executable": "/usr/bin/go"}
2022-11-21T09:56:12.778-0800    INFO    builder/main.go:76      Sources created {"path": "./bin"}

What did you see instead?
See description, I saw \n instead of newlines, etc

What version did you use?
4565692

Environment
OS: Ubuntu

Additional context
The problem is here:

opentelemetry-collector/internal/builder/main.go

Line 101 in fb510a9

return fmt.Errorf("failed to compile the OpenTelemetry Collector distribution: %w. Output: %q", err, out)

but I think there are also other instances in that file.

It has annoyed me as well, thanks for taking care of this!
