The #T is redundant.

Couldn't we fetch the fixtures ourselves with a secondary origin,
like I did here? <https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/golang.scm#n10561>

Update this to modern Guix style, please:

  #~(modify-phases %standard-phases
      (add-after 'unpack 'delete-cargo-lock
        (lambda _
          (delete-file "Cargo.lock")))
      (replace 'install
        (lambda* (#:key outputs #:allow-other-keys)
          (let ((bin (string-append #$output "/bin")))
            (mkdir-p bin)
            (install-file "target/release/tree-sitter" bin)))))
