rakudo.org website install from source instruction broken

[librasteve]

This page:

https://rakudo.org/star/source

States:

echo "export PATH=$(pwd)/bin/:$(pwd)/share/perl6/site/bin:$(pwd)/share/perl6/vendor/bin:$(pwd)/share/perl6/core/bin:\$PATH" >> ~/.bashrc

But:
$(pwd)/bin/: <= this has a TRAILING SLASH
That gives this:
which raku => /root/rakudo/bin//raku <= this has TWO SLASHES

May trip up unsuspecting users...

On a related note, when using Dockerfile one is in /bin/sh and this seems to choke on mkdir ~/rakudo && cd $_ so perhaps mkdir ~/rakudo && cd ~/rakudo would be more helpful

The trailing slash has been removed here: f9edbb8

cd $_ should be removed here: #90

Is there anything else? :)
