docs(terraform/provider): the provider now ships at the LiteLLM version

[yuneng-berri]

Relevant issues

Companion to the release-pipeline change that publishes the Terraform provider in lockstep with LiteLLM (BerriAI/project-releaser#201).

What

The provider is now published at the LiteLLM version, from the same commit as the proxy, on every LiteLLM release (dev, rc, stable) — the same way the terraform-aws-litellm / terraform-google-litellm modules already are. The 0.x line ends at 0.4.0.

This PR updates the provider's own docs and goreleaser config to match:

• RELEASING.md: the old "cut a CHANGELOG heading, the next release dispatches it" flow is gone; describes the lockstep flow, what a change needs, and how to recover a version whose goreleaser run failed. GPG setup and troubleshooting reference material is kept.
• README.md: new Versioning section; example pin updated; notes that a ~> 0.4 constraint will not receive further releases and should be re-pinned to the LiteLLM version.
• CHANGELOG.md: headings no longer drive releases; [Unreleased] records the versioning change.
• .goreleaser.yml: prerelease: auto, so v1.99.0-dev.1 / v1.99.0-rc.1 tags in the mirror are marked pre-release instead of becoming the repo's "Latest release". Registry ingestion is unaffected either way.

Greptile Summary

The PR aligns the Terraform provider’s documentation and GoReleaser configuration with lockstep LiteLLM releases.

• Documents the transition from the independent 0.x provider line to LiteLLM-aligned versions
• Updates provider pinning examples and prerelease guidance
• Replaces the old changelog-driven release procedure with the componentized release and recovery flow
• Marks dev and release-candidate GitHub releases as prereleases automatically

Confidence Score: 5/5

The PR appears safe to merge, with no concrete blocking or non-blocking defects identified in the changed configuration or documentation.

The GoReleaser setting matches the declared configuration schema and documented tag formats, while the documentation changes consistently describe the new lockstep versioning and release process.
