Upgrade dependent packages to the latest version

[yhatt]

This PR will upgrade dependent packages to the latest version via yarn upgrade --latest, excepted @types/vscode. It includes Marp Core v0.15.1 and Marp CLI v0.16.0 Marp CLI v0.16.1.

Notable changes

• Since Marp Core v0.14.0, it injects inline helper script for browser context. However, VS Code preview pane will restrict execution of the unknown inline script. The script has already executed in preview.js so we have to set script: false to prevent injection.

• Marp Core v0.15.0 and Marp CLI v0.16.0 supports GFM strikethrough syntax. It has compatibillity with the default Markdown syntax of VS Code but may break existing slides.

import browserCjs from '@marp-team/marp-core/lib/browser.cjs'

Since Marp Core v0.14.0, the entry point for browser context was replaced into @marp-team/marp-core/browser.

import browser from '@marp-team/marp-core/browser'

However, the result (bundled through rollup-plugin-commonjs) is incorrect. It may be related to rollup/rollup-plugin-commonjs#414.

We can still use the same entrypoint (designed for internal usage) to avoid this issue.
