Updating Decimal version requirement

I've tested this upgrade against https://github.com/etalab/transport-site.

Things look fine here - but FYI I noticed 2 unrelated problems:

• Elixir 1.19 appears to bring in failures due to how series inspect is affected
• the upgrade to Polars 0.52 broke a bit of code

So LGTM (and thanks for the bump), will open issues for those 2 issues.

@thbar I think I addressed both of those issues in https://github.com/elixir-explorer/explorer/tree/1141-cloud-integration-tests-are-broken-in-ci but I am still working through Linux tests seg faulting. That branch also upgrades to Polars 0.53. I’ll get back to work on that branch after I am back from vacation in a couple of weeks, unless you want to take a stab at it?

I'll try to look into it before you're back (no hard promise, but possible).

One thing caught my eye: the Rust version is fairly old and out of sync with what Polars uses today:

explorer/native/explorer/rust-toolchain.toml

Line 4 in aea455c

channel = "nightly-2025-10-24"

Would you be OK with me bumping it to the latest non-nightly at least? I'm not familiar enough with the setup, but I wonder if that could actually fix the segfaults.
