bug#65006: 29.1.50; c-ts-mode: else block not indented right on TAB

[Mohammed Sadiq]

The else block in the following code is not indented on TAB:

int
main (void)
{
  if (true)
    do_something ();
  else
do_something_else ();
}

How to reproduce:
1. Select the complete buffer
2. Press TAB

Expected result:
do_something_else() should be indented

afair, this did seem to work in the past.  May be this
happened after I updated treesitter-c module, idk.
