kubetail 0.0.2 (new formula)

Kubetail is a tool for viewing logs from multiple Kubernetes
pods simultaneously. This commit adds a new formula for the
Kubetail CLI executable (`kubetail`).

The formula has the following features:

- Builds frontend (Typescript/React) from source using pnpm and
  the backend from source using Go
- Adds shell completions from the executable
- Uses executable's built-in `serve --test` subcommand for testing
