### Description of Request

Requesting a Slack channel for the newly-forming Thai (th) localization of the Kubernetes documentation, following the same pattern as existing localization channels (e.g. kubernetes-docs-id, kubernetes-docs-ko, kubernetes-docs-fa).

We are members of #sig-docs and #sig-docs-localizations, and have landed a first contribution (Thai translation of the CNCF Code of Conduct, merged: cncf/foundation#1479). We're about to post an announcement in #sig-docs-localizations and would like this channel available for the team to coordinate the localization launch per https://kubernetes.io/docs/contribute/localization/.

### Justification for Request

A dedicated channel lets the Thai localization team coordinate translation work, PR reviews, and terminology decisions without adding noise to the general #sig-docs-localizations channel. It's the same pattern other active language teams (e.g. Indonesian, Korean, Portuguese) already use, and gives SIG Docs a clear, persistent place to track this effort as the contributor base grows.

Start by reviewing the localization guidance at https://kubernetes.io/docs/contribute/localization/ and the existing #kubernetes-docs-id, #kubernetes-docs-ko, and #kubernetes-docs-fa channel pattern. Confirm the Thai team’s coordination in #sig-docs and #sig-docs-localizations, then request or create kubernetes-docs-th; done means the dedicated channel is available for the localization launch.
