`nextflow lint` breaks when reporting certain syntax errors

Bug report

From this Slack thread: https://nextflow.slack.com/archives/C02TPSL19UJ/p1765881373697229

The following test cases have syntax errors:

// nextflow.config
process {
  withLabel:
  'bambino' {
    container = "..."
  }
}

process SEQTK_SAMPLE {

  script:
  """
  ${
    params.is_paired_end
    ? "..."
    : "..."
  }
  """
}

Expected behavior and actual behavior

The linter should report syntax errors for both snippets (the language sever reports them correctly).

Instead it fails with an error like this:

java.lang.StringIndexOutOfBoundsException: Range [12, 13) out of bounds for length 12
	at ...
	at java.base/java.lang.String.substring(String.java:2834)
	at nextflow.script.parser.v2.StandardErrorListener.printCodeBlock(ErrorListener.groovy:187)
