github-queries.js: declare constants as const

[praaatap]

Title

Remove var and use const, add semicolons

Description

This change enhances the JavaScript coding style and ensures the variables are safe.

Changes made

1. Replaced var with const in variable declarations.
2. Declared variables correctly instead of leaving them undeclared.
3. Added missing semicolons to adhere to the standard JavaScript coding style.
4. No functionality was altered. The code functionality is still the same.

Why this change

const is safer than var because it does not allow the variables to be reassigned by mistake.
Adding semicolons also enhances the code readability.

Summary

This commit only enhances code quality. It updates the coding style of the variables and formatting without altering the functionality of the program.

Thanks! I resolved the conflicts.

This is rather trivial and does not affect functionality, but why not.
