More Cleanup in Preparation for Usage with Lumino

[jtpio]

• Do not require tags to exist in the branch for changelog generation
• Skip node_modules files when checking links
• Print current changelog entry in draft_changelog
• Handle workspaces metadata being a dict (jupyterlab currently) or a list (lumino currently)
• Pin tomlkit since it 0.7.1 breaks tbump
