This updates the instructions to open the Developer Tools in the issue template,
as the keyboard shortcuts have changed to their defaults on Linux & Windows
from [Ctrl]+[Alt]+[I] to [Ctrl]+[Shift]+[I].
Further, the editor config is updated to allow trailing spaces in Markdown
files to add trailing spaces to the list items in the issue template, in
order to avoid people not putting whitespace in between, causing the formatting
to not be parsed properly.
Change-Type: patch
Additionally, we setup an EditorConfig rule to automatically switch to
tab style on Makefile.
