Add YAML view for Get-PSRuleBaseline

[BernieWhite]

Currently Get-PSRuleBaseline returns a complex object of the baseline. Add an additional option to return the baseline as YAML, for example -OutputFormat Yaml.

@BernieWhite I can probably help with this. I had a first go and was able to get this output(only first 100 lines):

              name: Replace
              isInstance: true
            - memberType: Method
              overloadDefinitions:
              - string[] Split(char separator, System.StringSplitOptions options)
              - string[] Split(char separator, int count, System.StringSplitOptions options)
              - string[] Split(Params char[] separator)
              - string[] Split(char[] separator, int count)
              - string[] Split(char[] separator, System.StringSplitOptions options)
              - string[] Split(char[] separator, int count, System.StringSplitOptions options)
              - string[] Split(string separator, System.StringSplitOptions options)
              - string[] Split(string separator, int count, System.StringSplitOptions options)

But it seems there are some serialization problems with the tags and some other things like the method overloads showing up in the output.

Seems like an issue how hashtables are getting serialized. Could probably create a YAML converter to handle this.

@ArmaanMcleod Great thanks. Yes, you may need to customise the serialization process. Ideally, we want it to look the original object.

https://github.com/Azure/PSRule.Rules.Azure/blob/cfc0b4974dff48123582002e66455206cdac8660/src/PSRule.Rules.Azure/rules/Baseline.Rule.yaml#L9-L17

Extra properties such as id, source, info and baselineId can be removed from serialized object.
