fix(ci): release site version check

[universal-itengineer]

Description

Update the release-site version checker to read module versions from the module-specific page:

https://releases.deckhouse.io/modules/virtualization

The checker now parses editions from that page and validates the requested channel column there, instead of scraping separate edition pages (/fe, /ee, /ce, /se-plus). The Taskfile description was updated to point to the same URL.

This also aligns the tools/moduleversions Go directive with the workflow Go version: 1.25.10.

Why do we need it, and what problem does it solve?

The old parser depended on the HTML layout of edition pages and failed with version not found even when the version was already published for the module. This caused false CI failures during release-channel validation.

Using the module-specific page matches the data we need directly: one module, all editions, all release channels.

What is the expected result?

check:releases should pass when the requested module version is present on the module release page for the selected channel.

Verified locally with:

go run ./main.go moduleversions --channel alpha --version v1.8.2 --attempt 1 --check-releases
go test ./...
