chore(docusaurus): upgrade to v3.7.0

[thetaPC]

Issue URL: internal

What is the current behavior?

Docs is using Docusaurus v3.0.1.

What is the new behavior?

Updated to the latest Docusaurus

• Updated the swizzled files to have the latest content
• Removed the Books page. It was causing the docs site to fail to compile due to a link issue. Instead of fixing it, it was removed since anyone with that page link gets redirected to an external site so there's no need to keep it.
• Enabled the version status banner. This will render a banner stating that the selected version is no longer being maintained. This would make it easier for developers to know which version is up to date. This banner can be seen when v7 is selected.

Does this introduce a breaking change?

• Yes
• No

Looks good to me 🚀

This looks good but can the banner text be changed? Maybe like:

-This is documentation for Ionic Documentation v7, which is no longer actively maintained.
+This is the documentation for Ionic Framework v7, which is no longer actively maintained.
-For up-to-date documentation, see the [latest version](https://ionic-docs-git-docusaurus-upgrade-ionic1.vercel.app/docs/) (v8).
+For the most up-to-date documentation, see the [latest version](https://ionic-docs-git-docusaurus-upgrade-ionic1.vercel.app/docs/) (v8).

Discussed offline regarding the banner text. Since it would consist of swizzling the component, it was decided to leave it alone. The site title was updated to reflect accurately on the banner: fbb9ccd
