Fix for new simplecov results

[szechyjs]

Bug fix

Description

Simplecov changed the .last_run.json file.

Fixes #5

Also fixed a spelling typo.

Why should this be added

Without this the action errors:

/action/lib/report_adapter.rb:10:in `conslusion': undefined method `>=' for nil:NilClass (NoMethodError)
	from /action/lib/github_check_run_service.rb:20:in `run'
	from /action/lib/index.rb:29:in `<main>'

Checklist

This looks good. Supports old and new syntax.

This fixes the /action/lib/report_adapter.rb:10:in conslusion': undefined method >=' for nil:NilClass though I'm not seeing the screenshots as part of the Github Action output. Does anyone know if that still works?

Is it perhaps to do with permissions or private repo?
