[5.3] Installer rtl logical css

[brianteeman]

At some point in time a change was made and the post scss rtlcss started processing the installation template scss files so it was actually reversing everything - doh - so any directives in the current rtl-scss were being reverted by rtlcss

Summary of Changes

Made sure the installation template uses logical css properties (-start, -end instead of -left, -right)
Fixed the css generation so that the rtlcss now works as intended - thanks @dgrammatiko
Removed all overrides from template-rtl,scss as they are not needed with logical css and a working rtlcss processing

Testing Instructions

Apply pr and npm run build:css or use a pre-built package
Check everything "looks" ok in both LTR and RTL languages

  const options = shouldSilenceDeprecation(file) ? { silenceDeprecations: ['mixed-decls', 'color-functions', 'import', 'global-builtin'] } : {};

and change const { css } = await compileAsync(file, options); to const { css } = await compileAsync(file);
