Some 404 not found broken links in our docs need to be cleaned up.

@jbampton on it, do we need to clear it out or update to real links?

Hello @Brijeshthummar02 I found these broken links today.

I am not sure what the correct links should be.

It would be best to find the correct current online links.

It is also possible to use The Wayback Machine to find old versions of web pages and files etc that are no longer live for example for the 404 on the PDF file.

Also while going through the markdown files i saw tones of lint issues if u want i can handle it, small req would be good if you provide me the above correct links as i am not knowing much about repo.

Let us keep each PR self contained and focused on just one issue.

So if you want to fix Markdown lint issues do that in a second PR.

We already have lots of linters running with pre-commit including markdownlint.

Whilst it is nice to clean up the docs it is better to also add a check / test to enforce these cleans ups in future and to stop regressions.

So the markdownlint config is here: https://github.com/apache/sedona/blob/master/.github/linters/.markdown-lint.yml

The pre-commit config is in the repo root.

@jiayuasu may i get the correct link so that i can fix it.
