parser: token `map_value_ind` handled incorrectly inside a scalar (str)

[perillo]

Here is a simple example:

test:
  time: 04:30

$ zig build run -- test.yaml
debug(tokenizer): Tokenizer.Token{ .id = Tokenizer.Token.Id.literal, .start = 0, .end = 4 }
debug(tokenizer):     | test
debug(tokenizer): Tokenizer.Token{ .id = Tokenizer.Token.Id.map_value_ind, .start = 4, .end = 5 }
debug(tokenizer):     | :
debug(tokenizer): Tokenizer.Token{ .id = Tokenizer.Token.Id.new_line, .start = 5, .end = 6 }
debug(tokenizer):     | 

debug(tokenizer): Tokenizer.Token{ .id = Tokenizer.Token.Id.space, .start = 6, .end = 8 }
debug(tokenizer):     |   
debug(tokenizer): Tokenizer.Token{ .id = Tokenizer.Token.Id.literal, .start = 8, .end = 12 }
debug(tokenizer):     | time
debug(tokenizer): Tokenizer.Token{ .id = Tokenizer.Token.Id.map_value_ind, .start = 12, .end = 13 }
