figure crossreference doesn't work when label has uppercase letters anywhere in it

Bug description

Cross reference does not work when figure label has a uppercase letters in it.

Steps to reproduce

---
engine: julia
---

```{julia}
using CairoMakie
```

This is a reference to @fig-0x4a59ab6a-okay (works)

```{julia}
#| echo: fenced
#| label: fig-0x4a59ab6a-okay
#| fig-cap: "Just a caption"

xs = rand(50) * 2pi
ys = sin.(xs)
scatter(xs, ys)
```

This is a reference to @fig-0x7b2ada84-Okay (does not work)

```{julia}
#| echo: fenced
#| label: fig-0x7b2ada84-Okay
#| fig-cap: "Just a caption"

xs = rand(50) * 2pi
ys = sin.(xs)
scatter(xs, ys)
```

This is a reference to @fig-0xdd9b4a13-notbad (works)

```{julia}
#| echo: fenced
#| label: fig-0xdd9b4a13-notbad
#| fig-cap: "Just a caption"

xs = rand(50) * 2pi
ys = sin.(xs)
scatter(xs, ys)
```

This is a reference to @fig-0xdd9ca19d-nOtbad (does not work)

```{julia}
#| echo: fenced
#| label: fig-0xdd9ca19d-nOtbad
#| fig-cap: "Just a caption"

xs = rand(50) * 2pi
ys = sin.(xs)
scatter(xs, ys)
```

Expected behavior

Any string sequence after fig- should be a valid identifier

Actual behavior

Get missing reference in document.
