 The file `data/W.lean` shows that if `α` is an an encodable fintype and for every `a : α`,
 `β a` is encodable, then `W β` is encodable.

style: homogenise porting notes (#11145)

Homogenises porting notes via capitalisation and addition of whitespace.

It makes the following changes:

converts "--porting note" into "-- Porting note";
converts "porting note" into "Porting note".

chore(Topology/{Paracompact + PartitionOfUnity + Algebra/Order/Compact}): restore a more faithful mathported proof, using the "newer" push_neg (#5132)

These are just three cases where a mathported proof had to be changed, due to unwanted behaviour with push_neg/contradiction. Since #5082 is supposed to fix some issues with these tactics, some of these workarounds can be removed.

Note: this was not in any way systematic, I simply grepped the line after a contra, then grepped for a not and then selected 3 likely candidates. There are potentially more situations like these.
