fix(installation): Fix rustlings installation check

fixes #147

I did some quick testing with the `-x` check:

```sh
if [ -x "$(notrustlings)" ]
then
    echo "notrustlings does not exist"
else
    echo "notrustlings appears to exist!"
    notrustlings
fi
```

which produced:

```
./test.sh: line 12: notrustlings: command not found
notrustlings appears to exist!
./test.sh: line 17: notrustlings: command not found
```

(consistent with comments in issue)

Using `if ! [ -x "$(command -v <command>)" ]` appears to be the standard way to perform this type of check.
