bug: Non-local error on single "-" in value

[qvalentin]

Did you check existing issues?

• I have read all the tree-sitter docs if it relates to using the parser
• I have searched the existing issues

Tree-Sitter CLI Version, if relevant (output of tree-sitter --version)

Describe the bug

A value consisting of just a single dash, will cause the syntax to raise a non-local error, causing syntax highlighting for the rest of the file to break.

Steps To Reproduce/Bad Parse Tree

hi: test
hi2: -
hi3: test

This is probably not valid yaml.

(ERROR ; [0, 0] - [1, 4]
  (block_mapping_pair ; [0, 0] - [0, 8]
    key: (flow_node ; [0, 0] - [0, 2]
      (plain_scalar ; [0, 0] - [0, 2]
        (string_scalar))) ; [0, 0] - [0, 2]
    value: (flow_node ; [0, 4] - [0, 8]
      (plain_scalar ; [0, 4] - [0, 8]
        (string_scalar)))) ; [0, 4] - [0, 8]
  (block_mapping_pair ; [1, 0] - [1, 4]
    key: (flow_node ; [1, 0] - [1, 3]
      (plain_scalar ; [1, 0] - [1, 3]
        (string_scalar))))) ; [1, 0] - [1, 3]

Expected Behavior/Parse Tree

A local error in the block_mapping_pair node.
