chore(nano): depin deno version from 1.45.4

A regression was introduced in Deno `1.45.5`, which breaks handshake with MongoDB Server.

See [here](https://github.com/denoland/deno/issues/24841). Pinning to 1.45.4 circumvents the issue, for now.

Seeing as `nano` uses the MongoDB hyper `Data` adapter, we need to hardpin the Deno version compiled with the nano binaries.

Once this regression is fixed in Deno, we can depin the version used in the compiled binaries for nano

Start by locating the nano binary build configuration and the Deno version declaration. Pin the compiled binaries to Deno 1.45.4, then verify that the build uses that version and preserves the documented path to depin it after the regression is fixed.
