docs (level 101): fix typos, punctuation, formatting

[grjan7]

This PR includes significant edits to the Level 101 docs to improve the readability in the context of following:

• formatting of code snippets inline and in blocks
• capitalization of SQL commands in the code blocks to differentiate them from dbs, tables, columns and fields
• typos
• added tab spaces to indent sublists
• added links
• punctuation

thanks for the PR :)

were these changes auto-generated or assisted by some tooling? The sheer volume of it makes it hard to review it all. And I wouldn't want to merge until someone has gone through them all.

does the backquote not work here? why introduce html tags?

[grjan7]

Backticks (```) in lists render the multiline code blocks as run-on inline. (The below snap is from https://linkedin.github.io/school-of-sre/level101/big_data/evolution/)

I agree it is huge to process. It's neither auto-generated nor assisted by any tooling. I've just read them line-by-line and compared against the rendered output as well.

It does not alter the content. However, it includes capitalization, formatting, indentation and few typos.
