feat: better error message for "unknown" tactic
...
@Kha The hack I posted at Zulip didn't really work
```
macro x:ident : tactic => throw $ Lean.Macro.Exception.error x s!"unknown tactic '{x.getId}'"
```
For example, we would still get a weird error message at
```
theorem ex3 (x : Nat) : x = x → x = x :=
have x = x by foo (aaa bbb) -- The error would be at `bbb`
fun h => h
```
There were other minor issues that could be fixed, but this one was bad.

feat: indented by
...
@Kha This one is not as useful as the indented `do`. When writing
interactive proofs I like the error message at the `}` showing the
resulting tactic state. We can simulate it using a `skip` in the end of the sequence :)
We remove the `skip` when the proof is done. Note that, the last `;`
is usually not part of the `by`. Example:
```lean
theorem ex (x y z : Nat) : y = z → y = x → x = z :=
fun _ _ =>
have x = y by apply Eq.symm; assumption; -- <<< the last `;` is part of the `have`
Eq.trans this (by assumption)
```
