Fix another Renovate blind spot; bump configure_conan's stale conan-version default (#137)

configure_conan/action.yml also defines conan-version with a nested
default (conan-version: / description: "..." / default: 2.3.1) --
a third shape the previous 2-line-specific regex (type: string /
default:) didn't cover, so this default silently stayed at 2.3.1
while every other conan-version default got bumped.

Generalized the customManager regex to match 'default:' appearing
anywhere within 80 chars after the key, instead of requiring an
exact 'type: string' line -- covers the workflow_call.inputs shape
and the composite-action-input shape (and any future variation)
with one pattern. Bumped the default itself to 2.31.2 to match.

Any downstream repo that calls .github/actions/configure_conan
directly with an explicit conan-version override (rather than going
through the top-level publish-*/abi-diff workflows) was relying on
this 2.3.1 default whenever the composite action's own default
applied -- worth checking those repos separately.
