[Makefile] Impossible to setup on Windows

Describe the problem

website/Makefile

Lines 172 to 173 in 5494bf1

	clean:
	rm -rf _site .jekyll* src/.jekyll* *.log tmp .dart_tool

Since most of the commands start with clean, there is no way to run rm on Windows command lines.

Also, copying Flutter from the host will cause platform issues that unable to start any Flutter commands.

@AlexV525 : Your second issue is a Windows Git issue.

Check out this StackOverflow post that explains the issue.

TL;DR: Git translated UNIX line breaks to Windows line breaks on git clone. bash has no idea what to do with those line breaks.

$ git config --global core.autocrlf input

That ensured that all writes to git and GitHub use LF only.

$ git config --global core.autocrlf false

This ensures that all reads to git and GitHub use LF only.

A deeper dive can be found on this GitHub page.

@AlexV525 : Your second issue is a Windows Git issue.

It's unfriendly to ask users to reconfigure their global configurations if they're not unnecessary, like Git, if the step can be done to solve them externally.
