Rename dispatch to send for consistency with TCA

[jonekdahl]

Summary

As discussed in #23, using send instead of dispatch would be beneficial for individuals and teams that have previous experience with TCA (The Composable Architecture). This PR changes the name to send, deprecating the dispatch methods.

Technical considerations

Tests

Existing tests have been updated. No new tests have been added since this is just a rename that doesn't introduce any new behavior.

Review pointers

As suggested by @semanticer, @Deprecated annotations were added, I hope I did them correctly.

I'm sorry for the late review and thanks again for this valuable contribution.

Nothing seems to be broken, all the changes are correct IMO and I tested whether @Deprecation annotation works and it does 👍

However, by searching the whole project for "dispatch" I discovered many other places we should probably fix. It's mostly in the docs, comments or tests but we should also probably rename those
dispatchFn: (List<Action>) -> Unit
as well right? @toggl/androids

Hi @semanticer! Are you expecting feedback from @toggl/androids or can I go ahead and do the changes you propose?

Sorry that it's taking so long @jonekdahl

Yeah, it'd be good to have these changed as well to avoid confusion.

[semanticer]

Hey @jonekdahl should I finish this or do you want to do the last changes yourself?

[jonekdahl]

@semanticer Go ahead!
