chore: bump app version 9 -> 10 (#5073)

## Describe your changes
Bumps the protocol version to denote the addition of LQT functionality.
Also bumps the crate versions from 1.0.x -> 2.0.x, as an alpha. No tag
has been created, to avoid triggering the formal release workflows,
since we're still testing.

## Issue ticket number and link

#5010.

## Testing and review

I'm submitting this PR ahead of a planned testnet upgrade, so we'll
shortly learn how effective the overall upgrade process is. However,
special attention should be given to the proposed versions strings. In
particular, the transition from `0.81.x` to `1.0.x` maintained
compatibility with APP_VERSION 9, and that may present difficulties
during the upgrade for nodes on one or the other version.

## Checklist before requesting a review

- [x] I have added guiding text to explain how a reviewer should test
these changes.

- [x] If this code contains consensus-breaking changes, I have added the
"consensus-breaking" label. Otherwise, I declare my belief that there
are not consensus-breaking changes, for the following reason:

> explicitly denotes consensus-breaking changes, and therefore targets a
protocol feature branch, rather than main
