wendelin.core: v↑ 2.0.alpha2.post2 -> 2.0.alpha3
New WC2 alpha release provides us with various small fixes:
https://lab.nexedi.com/nexedi/wendelin.core/compare/5e5ad598...7ce0978d
It also prepares upgrading SlapOS go default version to v1.18 (WC2 alpha2 doesn't work with go1.18). See https://lab.nexedi.com/nexedi/slapos/merge_requests/1305#note_175026.
Tests are pending: https://erp5js.nexedi.net/#/test_result_module/20221221-5FEF9030; let's see if they pass.
