[Bug] dts-gen causes an error if TypeScript isn't installed

[tasshi-me]

Summary

Related to kintone/js-sdk-ja#39.

The typescript dependency is missing on @kintone/dts-gen, so dts-gen causes an error during generating type definition file.

Target Package

@kintone/dts-gen

Target Version

v7.0.2

Reproduction

1. Install @kintone/dts-gen
2. Run dts-gen

yarn add -D @kintone/dts-gen
kintone-dts-gen --base-url $KINTONE_BASE_URL --api-token $KINTONE_API_TOKEN --app-id $APP_ID --type-name SampleFields --namespace company.name.types -o sample-fields.d.ts

Expected Behavior

User can execute dts-gen successfully without installing typescript manually.
(When installing dts-gen, typescript should be installed automatically)

Actual Behavior

The dts-gen causes an error.

@cybozu/eslint-config includes typescript (and eslint) in peerDeps, so we need to add typescript to our deps manually.

[tasshi-me]

We decided not to do any implementation to fix it.

TypeScript is specified in peerDeps of @cybozu/eslint-config.
npm and pnpm install peerDeps automatically.
This issue only happens with Yarn.
