TCH auto-quoting is invalid for strings containing quotation marks

[dscorbett]

The automated fixes for TCH001, TCH002, and TCH003 do not correctly handle string literals containing quotation marks. In the following example, running Ruff introduces an invalid type annotation, which mypy reports.

$ ruff --version
ruff 0.7.1

$ cat tch.py
from collections.abc import Sequence
from typing import Literal
def f(x: Sequence[Literal["'"]]) -> None:
    pass

$ mypy tch.py
Success: no issues found in 1 source file

$ ruff check --isolated --config 'lint.flake8-type-checking.quote-annotations = true' --select TCH tch.py --unsafe-fixes --fix
Found 1 error (1 fixed, 0 remaining).

$ cat tch.py
from typing import Literal, TYPE_CHECKING

if TYPE_CHECKING:
    from collections.abc import Sequence
def f(x: "Sequence[Literal[''']]") -> None:
    pass

$ mypy tch.py
tch.py:5: error: Invalid type comment or annotation  [valid-type]
