Describe the bug / provide steps to reproduce it

When writing a function name that starts with a capital letter in the editor, the syntax highlighter incorrectly identifies it as a type instead of a function. This results in the wrong color being applied to the function name, which is a bit confusing especially when using React.

This is not a theme specific issue, the bug occurs with all the themes.

Reproduction

Create a typescript file and paste this:

type ThisIsAType = {
	foo: 'bar';
};

function thisIsAFunction() {
	return 42;
}

// Same color as the type instead of the function
function ThisIsAFunctionNotAType() {
	return 42;
}

Environment

OS: macOS 14.6.1

Tree-sitter parses these identically ("debug: open syntax tree view" from the command palette) so I'm not sure where this getting mixed up, but I can reproduce.
