chore: migrate paste to maintained crate

[Mylloon]

I ran cargo-deny and got this output:

cargo deny check advisories
error[unmaintained]: paste - no longer maintained
205 │ paste 1.0.15 registry+https://github.com/rust-lang/crates.io-index
    │ ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ unmaintained advisory detected
    │
    ├ ID: RUSTSEC-2024-0436
    ├ Advisory: https://rustsec.org/advisories/RUSTSEC-2024-0436
    ├ The creator of the crate `paste` has stated in the [`README.md`](https://github.com/dtolnay/paste/blob/master/README.md) 
      that this project is not longer maintained as well as archived the repository
      
      ## Possible Alternative(s)
      
      - [pastey](https://crates.io/crates/pastey), a fork of paste and is aimed to be a drop-in replacement with additional features for paste crate
    ├ Announcement: https://github.com/dtolnay/paste
    ├ Solution: No safe upgrade is available!
    ├ paste v1.0.15
      └── lightningcss v1.0.0-alpha.67

So I changed the dependencie from paste to pastey.

For testing I compiled the project and ran cargo test.
