[fix][doc] Fix broken links in legacy docs

[momo-jun]

Motivation

Following #406, this PR aims to clean up the existing 404 issues in Pulsar legacy docs before 2.8.0.

Modifications

The major reasons for broken links in the legacy doc sets and related modifications in this PR are:

• the linked file is missing for unknown reasons - the files are added back using the nearest doc version.
• the linked file is invalid because the feature is unsupported in those earlier versions - these links are removed.
  I think some files have been overwritten by later versions unexpectly, for example, the doc version 2.2.0, 2.3.0 and 2.3.2 include content of TableView, which was introduced in 2.10.0.
• the linked file is in invalid format - these links are fixed.

Documentation

Some features were added to earlier versions. Have you double checked this with engineers?

[momo-jun]

As mentioned in the PR description, I do think the doc sets for 2.2.0, 2.3.0 and 2.3.2 (and maybe more) have been overwritten by later versions unexpectedly during the website upgrade in last May and include many newly added features, e.g., TableView (introduced in 2.10.0) - I've removed the TableView related content though, but I believe there are much more, and challenging to check and clean one by one this way.

It would be more effective if there is a way to directly trace back the specific original doc versions; otherwise, those three doc sets have a huge gap in aligning with features. It's another thread, though. I discussed this with @urfreespace but the answer was negative.

So this PR aims to clean up 404 issues only. Despite this, I've checked with engineers about the availability of several features, e.g., schema, pulsar manager, security, etc.
