Automatically wrap string expressions in condition in apostrophes

[thomhurst]

Take this variable condition:

        Variables =
        {
            StartsWith("refs/head/feature/", variables.Build.SourceBranch).Variable("myvariable", "pr-variable")
                .Else.Variable("myvariable", "other-variable"),
        },

The yaml being produced is:

variables:
- ${{ if startsWith($(Build.SourceBranch), refs/head/feature/) }}:
  - name: myvariable
    value: pr-variable
- ${{ else }}:
  - name: myvariable
    value: other-variable

I get this exception:

I think both of these values in the Contains/StartsWith/EndsWith conditions need to be made into strings. i.e. adding quotes around them

[thomhurst]

I've proposed this solution. Let me know if you think it's bad.

Thanks again for the contribution, @thomhurst! You can find the new updates in the 1.4.0 package.

Actually, with the if does not start with ' it's probably not even a breaking change but I have already tagged it like 1.4.0 so we have that now.
