A bug in explicit-member-accessibility when a member start with "#"

[HypnosNova]

Repro

{
    rules: {
        '@typescript-eslint/explicit-member-accessibility': 'error'
    }
};

class A {
    #aaa() {}
}

Expected Result
no error

Actual Result
shows that I musr add public or private before the method aaa()

The # means the member is private so we can't use public or private in this case.
