(devel/R-lintr) updated 2.0.0 to 2.0.1
# lintr 2.0.1

## New features

* Lintr now supports GitHub Actions and will print the lints as warning
  messages if lints are printed during an action.

## Minor fixes and features

* `single_quote_linter()` no longer causes a print issue when open quote
  appears at a column > than close quote (#457, @jamieRowen)
* `absolute_path_linter()` and `nonportable_path_linter()` now handle
  file-paths that are wrapped with double-quotes (#433, #437, @russHyde).
* `get_source_expressions()` has been changed to handle `expr_or_assign_or_help`
  tokens arising when parsing code containing equals-assignments in R-devel
  (#403, #456, @russHyde).
* `object_usage_linter` has been changed to ensure lint-position is indicated
  relative to the start of the file, rather than the start of a defining
  function (#432, @russHyde).
