`EnforcedStyleAlignWith: start_of_line` by default due to `||= begin` tends
by default. On the other hand, `Layout/BeginEndAlignment` cop aligns with
This `Layout/EndAlignment` cop aligns with keywords (e.g. `if`, `while`, `case`)
start of the line where the matching keyword appears.
If it’s set to ‘start_of_line`, the `end` shall be aligned with the
left-hand-side of the variable assignment, if there is one.
If it’s set to ‘variable` the `end` shall be aligned with the

Three modes are supported through the `EnforcedStyleAlignWith`
Checks whether the end keywords are aligned properly.
