Liquid/Nunjucks: Line numbers in error messages are incorrect

Operating system

Linux

Eleventy

2.0.1

Describe the bug

Stacktraces from errors in Markdown files give an incorrect line number. It appears that the length of the front matter is not taken into account.

Reproduction steps

Either use eleventy_repro.zip, or:
1. npm init
2. npm install --save @11ty/eleventy
3. Create file.md with the following content:
```
---
title: Title of the page
description: this is a description
---

{% doesnotexist %}
```
Run npx @11ty/eleventy

See the following error message mentions "line:2" but the error is on line 6.

Rename file.md to file.liquid or file.html. See same error occurs

Expected behavior

The error message should say the error is on line 6 of the file. Ideally, this should be given as a single path so it is clickable like: /home/ruben/dev/tmp/eleventy_repro/file.md:6
