Only parse correctly tagged (sql...) templates

[andersthuesen]

First and foremost, thank you for creating this project! 🔥
Tried it out with our codebase at work, and got a lot of errors just from template strings that were not meant for SQL queries.
Example:

[INFO] Scanning "./pages/api" for SQLs with extension Ts
checking generate types config None
error: internal compiler error: syntax error at or near "FAIL"
  --> <./pages/api/post/is_empty.ts>:16:9
   |
16 |         const test = `FAIL HAHAHA`;
   |         ^^^^^^^^^^^^^^^^^^^^^^^^^^^

Turning off query registration for Tpl expressions seems to do the trick!
Please let me know if you think this is a good idea 😄

Thanks for this PR, let me give it a try. That's weird, I've never got this error on my end. it could be that I've naively never tested against having some `some strings` strings in the tests and demo haha..

Reading the code, I wonder why did I do that there as I'm already extracting SQLs from get_sql_from_expr method 🤯

Hello, I tested the changes and it's all good. I will fix the failing tests after merging. It won't trigger any releases 👍

Thanks for your first contribution! (how did I miss this? #79)

The follow-up PR is #86

Please try v0.9.1+ for the fix
