fix(instrumentation)!: remove unused supportedVersions from Instrumentation interface

[blumamir]

The Instrumentation interface in the @opentelemetry/instrumentation class, contains a property supportedVersions?: string[] which is not used anywhere, not in the package itself or by any contrib instrumentation:

  /**
   * Contains all supported versions.
   * All versions must be compatible with [semver](https://semver.org/spec/v2.0.0.html) format.
   * If the version is not supported, we won't apply instrumentation patch (see `enable` method).
   * If omitted, all versions of the module will be patched.
   */
  supportedVersions?: string[];
}

It has no effect on anything really, just a property which downstream interface consumers can reference, and it is not set anywhere.

There exists 2 other configurations for supportedVersions here and here which are being used.

My investigation leads me to #1540 which added it to the interface but never used it. It uses the supportedVersions on each InstrumentationModuleDefinition, but the one in the Instrumentation interface was never utilized.

The comment on this property is also misleading and references (see enable method), but this function uses the other 2 supporetedVersions definitions on InstrumentationModuleFile and InstrumentationModuleDefinition but not the one which is commented.

Therefore, I think it is safe to remove it as a cleanup

I wonder if this is considered breaking change, as the property was never actually used, but it is part of a public interface therefore someone might have used it for any reason. very unlikely but possible.

I'd consider it breaking but I think it's a pretty acceptable change
