[FEAT] Better GitHub markdown reporting with emojis for checkmark ✅ and cross ❌

[bgalvao]

Is your feature request related to a problem? Please describe.

When I get a markdown report for GitHub, I get some native characters that don't stand out in the summary deepchecks report (cml markdown feature).

Describe the solution you'd like

For the emojis to show in the markdown in GitHub. Example screenshot 👇🏼

Solution is to find and replace the characters with their counterparts in GitHub markdown:

• ❌ (:x:)
• ✅ (:white_check_mark)

Additional context

I implemented this CML markdown feature last year. Guess I can improve it a bit.

Thanks for opening this @bgalvao! So essentially you're suggesting replacing what emojies are used in SuiteResultsave_as_cml_markdown? Can I assign this issue you you?
