Detects invalid types for tuple, list, bytes, string indices.
For example, the following will raise a `TypeError` at runtime and when
imported Python will display a `SyntaxWarning`
```python
var = [1, 2, 3]["x"]
```
```
example.py:1: SyntaxWarning: list indices must be integers or slices, not str; perhaps you missed a comma?
var = [1, 2, 3]["x"]
Traceback (most recent call last):
File "example.py", line 1, in <module>
var = [1, 2, 3]["x"]
~~~~~~~~~^^^^^
TypeError: list indices must be integers or slices, not str
```
Previously, Ruff would not report the invalid syntax but now a violation
will be reported. This does not apply to cases where a variable, call,
or complex expression is used in the index — detection is roughly
limited to static definitions, which matches Python's warnings.
```
❯ ./target/debug/ruff example.py --select RUF015 --show-source --no-cache
example.py:1:17: RUF015 Indexed access to type `list` uses type `str` instead of an integer or slice.
