Integrate with linear app API

[PI-Victor]

Context

Issue in linear don't link correctly with issues on github.

Description

Linear is peculiar about teams and projects and probably done on purpose for monetization. The bidirectional sync between the linear app and github can't be enabled because the issue created in linear ends up in the github repository that's the default for the team. So you can only create issue on github and they get synced on linear, but milestone, asignee, priority and most importantly, the project are not synced, so you have to manually add them. The issue just ends up in the backlog for the team.

Acceptance Criteria

These things are synced.

• project - an issue created in linear should sync with the right repo
• milestone - should be the same and created by the bot
• priority - can be done through labels
• the state - todo, backlog in progress, could also be synced through labels.
