Formatter: Multiline string followed by call expression

[MichaReiser]

I create this issue to document our decision on call expression formatting that directly follows a multiline string.

This is how stable black formats a multiline string

sql = """
INSERT INTO {0}_pony (pink, weight) VALUES (1, 3.55);
INSERT INTO {0}_pony (pink, weight) VALUES (3, 5.0);
""".format(
    app_label
)

But Ruff collapses the format call if it fits on the line

sql = """
INSERT INTO {0}_pony (pink, weight) VALUES (1, 3.55);
INSERT INTO {0}_pony (pink, weight) VALUES (3, 5.0);
""".format(app_label)

Ruff's formatting matches Black's preview improve multiline string handling formatting.

Ruff will only support the preview formatting because implementing the non-preview style requires specialised formatting that doesn't seem justified considering that this style will change soon anyway (and seems better IMO).
