Need to add devDependencies

[tbigueres]

Hello,

I've just tried to launch npm run build after npm install and I had the following error :

[email protected] lint
eslint src/

node:internal/modules/esm/resolve:844
throw new ERR_MODULE_NOT_FOUND(packageName, fileURLToPath(base), null);
^

Error [ERR_MODULE_NOT_FOUND]: Cannot find package '@medplum/bot-layer' imported from /Users/name/Documents/workspace/medplum-demo-bots/esbuild-script.mjs
at packageResolve (node:internal/modules/esm/resolve:844:9)
at moduleResolve (node:internal/modules/esm/resolve:901:20)

at ModuleWrap. (node:internal/modules/esm/module_job:85:39)
at link (node:internal/modules/esm/module_job:84:36) {
code: 'ERR_MODULE_NOT_FOUND'

I've managed to fix it by adding the @medplum/bot-layer to the devDependencies
