Subject: 29.0.60; wrong indentation will break the highlight on yaml-ts-mode

Hi Emacs dev team,

I found that when editing yaml file with yaml-ts-mode, the buffer
highlight will be break when the indentation of current line is wrong.

Steps to reproduce:

1. Start Emacs with `emacs -Q`
2. Open any a yaml file, such as `C-x, C-f ~/test.yaml`
3. M-x yaml-ts-mode, enable the yaml-ts-mode on test.yaml buffer
4. input the code below in the test.yaml buffer
```
values:
  a: 10
  b: 20
  c: 30
```
5. so far so good.
6. if the line 2 have a wrong indentation, such as four spaces in stead of
two spaces. Now the hightlight of line 3 and line 4 will be break
```
values:
    a: 10
  b: 20
  c: 30
```

The commit I built Emacs is f25c15ceb7d from emacs-29 branch.

Hi, and thanks for the report.

This is because the second incantation:
```
values:
    a: 10
  b: 20
  c: 30
```

is not valid YAML, and the parser reports an error.

Therefore I'm closing this bug since I don't think there's anything we can do here.
