chore: remove solo init command references (#301)

`solo init` has been removed from the Solo CLI (deprecated since v0.85.0,
removed in hiero-ledger/solo#5835). Remove references to it from the docs:

- Remove the `init → init` migration table row (the command no longer exists)
- Remove the `solo:init` task row from the Taskfile reference table

The CLI reference page (generated from the Solo CLI help output) will
automatically reflect the removal when the next docs build runs.
