Hookshot doesn't support experimental type stripping (aka native Typescript support) in Node 23

[Half-Shot]

At least, running the tests gives us:

$ yarn test
yarn run v1.22.22
$ mocha -r ts-node/register tests/init.ts 'tests/*.ts'  'tests/**/*.ts'
(node:202632) ExperimentalWarning: Type Stripping is an experimental feature and might change at any time
(Use `node --trace-warnings ...` to show where the warning was created)
(node:202632) [MODULE_TYPELESS_PACKAGE_JSON] Warning: Module type of file:///home/will/git/matrix-hookshot/tests/init.ts is not specified and it doesn't parse as CommonJS.
Reparsing as ES module because module syntax was detected. This incurs a performance overhead.
To eliminate this warning, add "type": "module" to /home/will/git/matrix-hookshot/package.json.
