Is there any simple way to remove Gutenberg editor H1 H5 H6 and change the label for the rest H2 H3 H4?

Before WP 5.9 it was possible to get rid of some heading types with CSS like this:

.block-library-heading-level-toolbar .components-toolbar-group {
    button:nth-child(1), button:nth-child(5), button:nth-child(6) {
        display: none;
    }
}

Since WP 5.9 the HTML code has changed. Now you can hide H1, H5 and H6 like this:

[aria-label="Heading 1"], [aria-label="Heading 5"], [aria-label="Heading 6"] {
    display: none;
}
