ISC rules do not conflict with the formatter anymore

[DimitriPapadopoulos]

Starting with ruff 0.9.0, ruff rule ISC001 is compatible with the ruff formatter:

• https://astral.sh/blog/ruff-v0.9.0#fewer-single-line-implicitly-concatenated-strings
• Remove formatter incompatibility warning for ISC001 astral-sh/ruff#15123

As for ISC002:

Formatter compatibility

Using this rule with allow-multiline = false can be incompatible with the formatter because the formatter can introduce new multi-line implicitly concatenated strings. We recommend to either:

• Enable ISC001 to disallow all implicit concatenated strings
• Setting allow-multiline = true
