PDF has bad display of code-line-numbers combined with code-block-border-left

Bug description

Description

When code-line-numbers is true and code-block-border-left is some color, the numbers overlay and overflow the border, resulting in something like this:

Steps to reproduce

File: mwe.qmd

---
title: "MWE"
format:
  pdf:
    code-line-numbers: true
    code-block-bg: false
    code-block-border-left: "#F0F0F0"
---


```{.python}
print("This is a MWE.")

while True:
    print("code-line-numbers and code-block-border-left mwe.")
```

Then run:

quarto render mwe.qmd --to pdf

Expected behavior

The numbers should not overlay the left border. Instead, they should be completely on its left, with some margin (something like what happens with the epub output). Or, alternatively, the numbers could overlay the border, but not overflow it. That is, the border width must large enough to accommodate the numbers within its limits.

Actual behavior

The numbers overlay and overflow the left border.

Start with the supplied mwe.qmd and render it using quarto render mwe.qmd --to pdf to reproduce the interaction between code-line-numbers and code-block-border-left. Trace the PDF rendering path responsible for code blocks and verify the result against the expected margin or contained-number behavior. Done means the reproduced PDF no longer has line numbers overflowing the left border.
