Expand build matrix for glibc

[IngwiePhoenix]

Is your feature request related to a problem? Please describe.
I am currently building a DevContainers environment for my work place and I noticed that SurrealDB's public releases are glibc only - whilst here, we have musl. On arm64 targets, I like to use musl, since on those boards I usually run Alpine. But here, in a DevContainer, I am on a x86 maschine - so, I can use full fat Debian (well, debian:bookworm-slim, to be precise).

I am not a Github Workflows expert, but I spotted this:
https://github.com/Odonno/surrealdb-migrations/blob/main/.github/workflows/release.yml#L17-L18

What if you were to add x86_64-unknown-linux-gnu?

Describe the solution you'd like
A small update to the release workflow to also include x86_64-unknown-linux-gnu as a target - so that one can grab binaries from the official SurrealDB repository and this repository without needing to wait for a Rust compile to finish.

Describe alternatives you've considered
None that come to mind, really.

Additional context
Got none :) Except to tag my work profile @senpro-ingwersenk for better tracking...

Unfortunately, x86_64-unknown-linux-gnu is not a valid/current target when using the rust-build/rust-build.action GitHub action.

I will try to switch to an alternate GitHub action that support more targets.

Huh, it really isn't o.o https://github.com/rust-build/rust-build.action?tab=readme-ov-file#supported-targets

That's quite a surprise. I'll dig around too, maybe I find something. If I am not wrong, I can test an actuion using the act tool. Should I find something I'll let you know :)
