Respect yamllint 'document_start' rule when autofixing yaml

[elara-leitstellentechnik]

Currently disabling document_start in the .yamllint config (see example below) file isn't applied correctly when autofixing yaml files since ansible specifies yaml version 1.1 which produces the following file header:

%YAML 1.1
---

While ansible-lint automatically removes the %YAML 1.1 line, the document start indicators are leftover.

Example .yamllint

rules:
  document-start:
    present: false
