[Merged by Bors] - chore(Combinatorics/SimpleGraph): rename Walks folder to Walk

[YaelDillies]

It is unusual to pluralise folder names, and furthermore this folder is about the Walk type.

• The relative value is the weighted sum of the differences with weight given by the inverse of the current value of the statistic.
• The absolute value is the relative value divided by the total sum of the inverses of the current values (i.e. the weighted average of the differences).

FWIW as of now 10% of the folders in mathlib end with an s (which usually implies they're pluralized, though not always)
I prefer Walks, but I'm okay with this change if the general trend is to stop pluralizing and rename those 10%.

Are these folders named after a type? Here, the SimpleGraph.Walk folder is named after the SimpleGraph.Walk type, which is a good property to have

Should we also rename Paths.lean since it's about the type Path?
(alternatively, can we deprecate Path and just use the unbundled IsPath?)

Sure, feel free to do so!
