fix(treesitter): don't forcefully open folds

Problem:
When `vim._foldupdate()` is invoked inside a scheduled callback, the
cursor may have moved to a line with a closed fold, e.g., after `dd` on
the line that is one line above a folded region. Then it opens the fold,
which is unnecessary and distracting. Legacy foldexprs do not have this
issue.

Solution:
Don't explicitly open folds on cursor.

Note:
This doesn't completely prevent spurious opening of folds. That is due
to bugs in treesitter foldexpr algorithm, which should be addressed
separately.
