Tooling updates (#37031)

Most of this is as everywhere else, but there's also interesting code
inspection fixes from the InspectCode bump, so I'll talk about that a
little.

## [Fix suspicious equality in
`Hotkey`](https://github.com/ppy/osu/commit/948136e49e88a721827d54e51c5759fe9aca811d)

Inspection:
https://www.jetbrains.com/help/resharper/TypeWithSuspiciousEqualityIsUsedInRecord.Global.html

Pretty annoying to fix, nullable array types are a pain. Does look legit
though.

## [Fix `StarDifficulty` using inefficient struct
equality](https://github.com/ppy/osu/commit/2db775ebb0bb9f18de67677ef84b993465d26545)

Inspection:
https://www.jetbrains.com/help/resharper/DefaultStructEqualityIsUsed.Global.html

This is a dodgy one because there's no real sane way to define equality
on `StarDifficulty` now that it has difficulty and performance
attributes jammed into it. So I just basically shut the inspection up
with a `record` modifier and move on.

Unclear where the equality is used precisely. It's from a global
inspection. F12 is very unhelpful when trying to track down usages of
`Equals()`. We definitely have `Bindable<StarDifficulty>` instances and
those do use equality. Maybe more than that.

## [Use `nameof` expressions to reference enum member
names](https://github.com/ppy/osu/commit/aa08175c803bc725f3b15a92174dfe6d1b812d91)

Inspection:
https://www.jetbrains.com/help/resharper/CanSimplifyDictionaryRemovingWithSingleCall.html

Pretty quaint.

## [Prefer using concrete values over `default` or
`new()`](https://github.com/ppy/osu/commit/b21ee08d7748be10d42268d5c2eb77369026545d)

Inspection:
https://www.jetbrains.com/help/resharper/PreferConcreteValueOverDefault.html

I could see this one going both ways, but I'm kinda sold on this
inspection. Explicit is always better. Saves some allocations in the
`CancellationToken` cases as well.

## [Explicitly call `.AsEnumerable()` in some realm
usages](https://github.com/ppy/osu/commit/c8ce1ecd42b9d8abb8b9e2ab93d471f463e80401)

Inspection:
https://www.jetbrains.com/help/resharper/PossibleUnintendedQueryableAsEnumerable.html

Not fully sold on this one but it's quick and simple so might as well.

## [Simplify dictionary removal with single `.Remove()`
call](https://github.com/ppy/osu/commit/5964ceccea900302df726b7a8ecbf6b74eb2e427)

Inspection:
https://www.jetbrains.com/help/resharper/CanSimplifyDictionaryRemovingWithSingleCall.html

Not much to say.
