Headings starting with numbers, e.g. # 1. My numbered heading do not qualify as sentence case.

Reproduction steps

1. Create a rule in your style for sentence case headings:

extends: capitalization
message: "'%s' should be in sentence case"
level: warning
scope: heading
match: $sentence

2. Create a number heading in a file

# 1. An important heading
Some text.

## An unimportant heading
Some text

3. Run vale with the rule from the style configured and observe the error.
