feat: add method check syntax

[louis820]

This PR changes two things :

• The Makefile now creates an unzipped version of the .wasm file
• There is a new wrapping for parsing a cel rule without any input, which only checks the syntax of the rule

Hi @louis820
Thanks a lot for the PR!

Just a couple of questions to better understand the changes:

1. Is the cel-syntax wrapper intended to be used by the UI?
   From what I can see, it’s not being called.

2. Any specific reason to version the uncompressed .wasm file?

Looking forward to your thoughts!

Hi @matheusfm ,
Thank you for your review.

I use this code for a project where I needed to run CEL rules in JS.
That's why I store the .wasm.gz file, so that I can copy it to my project to be used. I probably should have included it in gitignore though my bad.
I have not added the logic to use the wrapper in the UI since I only needed the backend version for my project.
