linter "did you mean..."

[CJ-Wright]

For some of the lints it would be helpful if the linter suggested the valid name.
Eg. for unexpected subsection name we could use a spell check algorithm to find the most likely spelling candidate (eg patch -> patches).

Basic idea
If https://github.com/conda-forge/conda-smithy/blob/master/conda_smithy/lint_recipe.py#L264 calculate the distance between the bad subsection and the expected subsections maybe using https://github.com/conda-forge/python-levenshtein-feedstock and if it is less than a threshold add a bit to the error asking if they meant one of the expected subsections.
