chore: tighten bounds for setuptools_scm (#3613)

there is a regression in 8.0.0 which results in the following invalid
code being generated for `vyper/version.py`:

```python
from __future__ import annotations
__version__ : str = version : str = '0.3.11'
__version_tuple__ : 'tuple[int | str, ...]' = \
  version_tuple : 'tuple[int | str, ...]' = (0, 3, 11)
```

this commit also removes some bad fuzzer deadlines.
