chore: drop the Bun support claim and its CI job (#60)

Bun does not load this addon. It refuses any file named
better_sqlite3.node ("'better-sqlite3' is not yet supported in Bun"),
and a renamed copy built for Bun's ABI (137) fails with undefined V8
symbols: Bun 1.3.5's V8 API layer lacks about 30 of the functions the
addon uses, among them FunctionTemplate::InstanceTemplate,
Function::Call, the Exception constructors and weak handles.

The test-bun job still passed because `bun run test` runs mocha through
its `#!/usr/bin/env node` shebang, so the tests ran under Node.

Remove the claim from the README, the bun engine from package.json, the
Bun troubleshooting section and the test-bun job.

 * Build the [bedrock](https://sqlite.org/src/timeline?r=bedrock) branch of SQLite to enable [`begin concurrent`](https://www.sqlite.org/src/doc/begin-concurrent/doc/begin_concurrent.md).
 * Create a shell too, so we can debug db files created
-* Supports both Node.js (22.x, 24.x) and Bun (>=1.1.0) runtimes
+* Supports Node.js 22.x and 24.x

-If you're using Bun and encounter issues:
-
-1. Ensure you're using Bun 1.1.0 or later
-2. Try rebuilding: `bun run build-release`
-3. Check that prebuilt binaries are available for your platform
-
-Note: Bun uses the same native module system as Node.js, so most Node.js troubleshooting steps apply.
