Describe the Bug

I am trying to set up a maximally strict pyrefly config. For that i use this:

[tool.pyrefly]
project-includes = ["src"]
project-excludes = ["tests"]
preset = "strict"
infer-with-first-use = true

[tool.pyrefly.errors]
implicit-abstract-class = "error"
missing-source = "error"
not-required-key-access = "error"
open-unpacking = "error"
unannotated-return = "error"
deprecated = "error"
implicit-import = "error"
non-exhaustive-match = "error"
redundant-cast = "error"
redundant-condition = "error"
unnecessary-comparison = "error"
unnecessary-type-conversion = "error"
unreachable = "error"
unreachable-match-case = "error"
unresolvable-dunder-all = "error"
untyped-import = "error"
variance-mismatch = "error"

However when i run pyrefly check i get this error

$ pyrefly check
 WARN Config at `.../pyproject.toml` failed to parse, checking with default configuration
ERROR .../pyproject.toml: TOML parse error at line 197, column 1

Fatal configuration error

Despite the docs clearly mentioning this confirugation option: https://pyrefly.org/en/docs/error-kinds/#unreachable-match-case

I am on version 1.0.0
