Cannot parse half brackets in doctests

[singularitti]

For example, I have code like this:

"""
    Lattice(data::AbstractMatrix)

Construct a `Lattice` from a matrix.

!!! note
    The basis vectors of the matrix are stored as columns.

# Examples
```jldoctest
julia> Lattice([
    1.2 4.5 7.8
    2.3 5.6 8.9
    3.4 6.7 9.1
])
3×3 Lattice{Float64}
 1.2  4.5  7.8
 2.3  5.6  8.9
 3.4  6.7  9.1
```
"""

and getting errors like this:

│ Subexpression:
│ 
│ Lattice([
│ 
│ Evaluated output:
│ 
│ ERROR: syntax: incomplete: premature end of input
│ Stacktrace:
│  [1] top-level scope

Similar to #328

I don't think this is related to JuliaSyntax as this same error happens on Julia 1.8.

I think the problem is just that the indentation in the doctest is broken and you need something like the following?

julia> Lattice([
           1.2 4.5 7.8
           2.3 5.6 8.9
           3.4 6.7 9.1
       ])
