Feature description

We currently updated to poetry to version 1.5 that introduced source priority. This has caused unexpected errors in our dependabot build. After further investigation of the dependabot-core codebase we think that there is no support for the latest poetry changes. ie (priorities) or the format produced by poetry is incompatible thus causing issue.

This is especialy important since the deprication messages outline the following

Warning: In a future version of Poetry, PyPI will be disabled automatically if at least one custom source is configured with another priority than 'explicit'. In order to avoid a breaking change and make your pyproject.toml forward compatible, add PyPI explicitly via 'poetry source add pypi'. By the way, this has the advantage that you can set the priority of PyPI as with any other source.

Addiitonlay suggesting to avoid using the secondary property and move over to the priority based sources.

Warning: Found deprecated priority 'secondary' for source ‘foo’ in pyproject.toml. Consider changing the priority to one of the non-deprecated values: 'default', 'primary', 'supplemental', 'explicit'.

I have raised an bug but I believe this could be escalated to a feature request : #7431

[[tool.poetry.source]]
url = "https://git.agilicus.com/api/v4/projects/328/packages/pypi/simple"
name = "common"
priority="primary"

[[tool.poetry.source]]
name = "PyPI"
priority = "primary"

this causes dependabot to break.
