Closes#10832
Note: This PR only fixes the issue where when entering one of `except`,
`finally`, `else`, and `elif` after another block like so:
```python
try:
for i in range(n):
pass
except:|
```
The `except` would be indented resulting in the following:
```python
try:
for i in range(n):
pass
except:|
```
This PR does not fix a separate issue in which the indentation is not
corrected from the second example to the first, i.e. if example 2 is
typed verbatim in Zed it will not auto-indent to look like example 1.
Handling of this case would likely require specific logic to handle, or
changes to the tree-sitter grammar for Python, as the current grammar
results in ERROR nodes that obscure the natural structure (cannot tie
the `except` to the `try`)
Release Notes:
- Fixed an issue where `except`, `finally`, `else`, and `elif` control
flow keywords in Python would be incorrectly indented when entered at
the correct level of indentation.
