Some lines in PEP 723 blocks trigger ERA001

Ruff (version 0.3.3) treats some lines from PEP 723 blocks as commented-out code.

```python
# /// script
# requires-python = ">=3.11"
# dependencies = [
#   "requests<3",
#   "rich",
# ]
# ///
```

```
$ ruff check --select=ERA001 pep723.py
pep723.py:3:1: ERA001 Found commented-out code
pep723.py:6:1: ERA001 Found commented-out code
