end region marker for html/xml should be #endregion

[eiswind]

the endregion marker in the regex for html/xml is #region

slidev/packages/slidev/node/syntax/transform/snippet.ts

Line 36 in ba6a004

[/^<!-- #?region ([\w*-]+) -->$/, /^<!-- #?region[\s\w*-]*-->$/],

i think it should be #endregion, at least this is what vscode expects.
