chore: Add permalinks to the cairo-by-example project

[mazurroman]

The cairo-by-examples project contains many Cairo code snippets. It would be great to add a link below relevant code snippets to open them in the Cairo playground on cairovm.codes so that devs can play with the code execution to understand it better.

cairovm.codes has a permalink feature, so that you can write some Cairo code and share it.

For the following code snippets, you should:

1. copy the code snippet into the Cairo playground of cairovm.codes,
2. generate a permalink,
3. add a “Open in Cairo playground” link pointing to the permalink, below the code snippet.

Acceptance criteria:
Create PRs on the cairo-by-example project with permalinks to cairovm.codes for the following code snippets:

• https://cairo-by-example.com/examples/if (the last snippet)
• https://cairo-by-example.com/examples/loop/
• https://cairo-by-example.com/examples/enums/
• https://cairo-by-example.com/examples/arrays (the full example in the last snippet)
• https://cairo-by-example.com/examples/dictionaries
• https://cairo-by-example.com/examples/clone_and_copy (the first snippet)
• https://cairo-by-example.com/examples/snapshots

Hi I am Jaipal (intro), i can take this issue. although i did check that cairovm.codes perma links contains some conflicting characters such as parenthisis which might mess with the markdown sytanx. i can encode them which should most definitely work if not might just shorten the links using dub.co (a good opensource link shortner) as the last resort if needed.

Just raised a PR #116 for this.
