Poetry plugins and other components for self add should be compatible with poetry.

[mbrancato]

When calling self add to install a plugin or authentication component, it would be a nice feature if Poetry would do a reverse compatibility check to ensure it attempts to install a version (when none is specified) that is compatible with self. Recent poetry releases for 2.0.x and 2.1.x have created some incompatibilities, but self add always tries to install the latest of the packages listed.

E.g.

Using Poetry 2.0.x, a user calls poetry self add my-plugin and it would install a version that is compatible with Poetry 2.0.x, but does not install a version that requires Poetry 2.1.x.
Using Poetry 2.1.x, a user calls poetry self add my-plugin and it would install a version that requires at least Poetry 2.1.x.
