new dac0a7adc44 Keep common.ai on anthropic 1.x until pydantic-ai supports
anthropic 2 (#75640)
dac0a7adc44 is described below
commit dac0a7adc44ee030d51fb562e6808e1036f8a22a

Keep common.ai on anthropic 1.x until pydantic-ai supports anthropic 2
(#75640)
pydantic-ai's Anthropic model (up to 2.59.0) calls BetaMessageParam(...),
which
anthropic 2 turned into a Union, so installing common.ai[anthropic] with
anthropic 2
fails with "Cannot instantiate typing.Union" on the first request.
Cap anthropic below 2 in the extra and the dev group.
