Fixes syntax for checking if pre-commit is installed in isaaclab.sh (#…

…1422)

# Description

When running `./isaaclab.sh --format` for another pull request, I got a
`command not found` error for `pre-commit`. Looking into the script, I
found a condition to check if `pre-commit` was installed, but the syntax
was off.

It was written like this:

```bash
if [ ! command -v pre-commit &>/dev/null ]; then
```

But it should be:

```bash
if ! command -v pre-commit &>/dev/null; then
```

I fixed it, and the script worked as expected, installing `pre-commit`
when I ran it again.

## Type of change
