Optional Fix for README

[miladsade96]

Separating navigating to stack directory and Adding to PATH
Because some of users may navigate to stack directory first and and enter this command(export PATH="$PATH:pwd/stack-2.1.3-linux-x86_64-static/) in order to install stack command that causes error below in $PATH:

No such file or directory

@everythingfunctional This reminds me of a question I wanted to ask about the instructions for installing stack: why does the README recommend following the 'Manual Download' instructions as opposed to using the simpler install script or distribution package managers? I used the Ubuntu distribution package followed by running $ stack upgrade which was much simpler and works fine.

The instructions for installing stack are pleasantly comprehensive (and cross-platform!) and I think we should simply refer users to this page and allow them to choose their preferred installation method.

I think this is a positive change, as our specific instruction was Linux only.

Thank you @milancurcic for approving this PR.

Thanks @everlookneversee , I agree this is an improvement.
Unless Brad had a specific reason for recommending the manual installation method, I think this is good to merge with one change: can you revert 7ee74b1?

Ok, I'll revert it.

@certik wanted to support people who didn't have sudo access to install system wide. I agree that the official stack install instructions are generally the preferred way, so I support this change. We may want to have a separate section to put the manual install instructions somewhere just in case.

I would like to keep it in some form, as requiring a sudo access is a non-starter on almost any machine where I would like to use fpm (I don't have sudo access).

I agree. Could this link just be mentioned to replace the deleted section. Furthermore, all OS are described there.

[certik]

I think that link would work.

@certik
What should we do for this PR?

[certik]

Looks good, thanks!

@certik Thanks for merging.
