Add emojis to `if-diff` output

[jmcook1186]

What Add a red cross emoji ❌ to the fail response and a green tick emoji ✅ to the success response for if-diff

Why This change makes the status of the if-diff response clear at a glance, especially when there are additional logs and warnings in the console.

Context if-diff is a command line tool we provide to enable rapid comparison of output files for debugging and verification purposes. Today it provides a success response as follows:

Files match!

and a failure response which looks like:

Files do not match!
tree.children.child-0.inputs.1.network/energy
source: 0.000001
target: 0.01

This plain text is adequate, but it would help to add an emoji to the console log to make it obvious at a glance whether the response was success/fail.

Prerequisites/resources none

SoW (scope of work)

• [ ] raise PR ading emoji to success and failure responses
• [ ] update unit tests as appropriate

Acceptance criteria

• [ ] if-diff success response is preceded by a green tick emoji in the console GIVEN the requested changes are made WHEN I run if-diff -s example.yml -t example.yml THEN I see the following output

✅ Files match!

• [ ] if-diff failure response is preceded by a red cross emoji in the console GIVEN the requested changes are made WHEN I run if-diff -s example.yml -t example-2.yml (where example.yml and example-2.yml differ) THEN I see the following output

❌ Files do not match!
tree.children.child-0.inputs.1.network/energy
source: 0.000001
target: 0.01

• [ ] All unit tests pass and have 100% coverage

Hi @jmcook1186

I'm looking for a good first issue to tackle, and this one seems within my reach. If it's still relevant, could you assign it to me?

Thanks :)
