Separate pip command syntax for notebook and CLI tabs in Quickstart

[pvelayudhan]

What does this PR do?

quicktour.md contains separate tabs for setting-up transformers in notebook and CLI environments, but presents notebook-style package installation (!pip install) regardless of which tab is selected. This commit updates quicktour.md to keep the pip install commands in the CLI tab and the !pip install commands in the notebook tab.

i think we can have an even simpler fix without duplicating content. keep everything as-is after the <hfoption> block and add a comment to the code snippets like:

# remove ! if installing from the CLI

I added this in, however after looking at it I get a feeling that it clashes with the existence of the notebook/CLI tab functionality. I know it appears redundant in the .md source, but I am wondering if you would reconsider keeping the original approach based on how the rendered version appears. If you still prefer just a comment on the pip line, that's fine with me!

i think they're two separate things here, the notebook/CLI tab offer different ways of logging in which is distinct from how to install PyTorch so i'd still prefer keeping it as a comment :)

we should also add the comment # remove ! if installing from the CLI to the code snippet below for installing the libraries

That makes sense to me, thank you for your response!

I have added in the second comment to cover both pip lines.
