adding afterStarted/beforeStart so MAUI Hybrid apps work

[LilahTovMoon]

MAUI Blazor Hybrid doesn't call beforeWebStart or afterWebStarted and instead calls beforeStart and afterStarted.

Note: I'm not an expert on this and the documentation, while noting the different initializers, doesn't really indicate why they're different (so there might be something I'm missing). There might be a reason not to do this (and if so I'd suspect that you'd know), but it does seem to work for me (for both web and MAUI).
