docs: fix broken links

[tasshi-me]

Why

Some relative links in our doc website are broken.

e.g. Stability Index to Versioning Policy

• expected link: https://cli.kintone.dev/community/versioning/
• actual link: https://cli.kintone.dev/community/stability-index/versioning (broken)

Root cause

There are two root causes: trailing slash and relative URL links.

trailing slash

By default, docusaurus generates /docs/myDoc/index.html for /docs/myDoc.md.
Amplify appends a trailing slash for the URL /docs/myDoc because /docs/myDoc.html doesn't exist.
Finally, accessing /docs/myDoc/ equals /docs/myDoc/index.html.

• Docusaurus: https://docusaurus.io/docs/api/docusaurus-config#trailingSlash
• Amplify: https://docs.aws.amazon.com/amplify/latest/userguide/redirect-rewrite-examples.html#trailing-slashes-and-clean-urls

trailingSlash: true is suitable for Amplify.

relative URL links

Specifying the trailingSlash: true will break some relative links.

We'd better use a file path rather than a URL path described in the reference.

What

• set trailingSlash: true
• replace relative URL paths with file paths.
