Make default status for new Linear issues configurable

[delucis]

Currently all new Linear issues default to “to do”, which may not make sense, especially in a PR context. Proposal to make this configurable when creating an issue from these three distinct scenarios:

• in an issue (to do by default)
• in a PR (in review by default)
• in a draft PR (in progress by default)

H/T @Princesseuh for the idea!
