[WiX] Remove an outdated educational note from Windows packaging.

[hborla]

I'm removing this note in swiftlang/swift@f1492fe; the restriction was lifted in SE-0362.

Starting in Swift 6.2, educational note identifiers should be stable and should not be removed in later toolchains. However, Swift 6.2 will be the first toolchain version to make that promise, so it's okay to clean up this educational note now.

I suppose that this is fine, though, I think that we could leave it in on main and only remove it on the release/6.1 branch as main is 6.2-dev.

We need to make sure this makes it to release/6.1 though.

I'm confused. I'm only removing the educational note on main, not on release/6.1.

Oh, sorry, I misunderstood the commit message. The first toolchain to guarantee the stability of edunotes is 6.2, not this feature. Ignore the message, LGTM!
