Banner cleanup - Removals after onboarding & new user experience audit
After the onboarding & new user experience audit, we have now have a first set of banners and alerts that was reviewed with @manav-gl, and that we are now removing asap. You can see the complete overview in our [Figma file](https://www.figma.com/design/MHgfNR68VAwfSVx53PV8UK/Banner-cleanup---Removals-after-onboarding---new-user-experience-audit?node-id=1-2&t=cd3rXzEnKTuzxGOP-1). Some of these will require further follow-ups to bring the content back to the page in a more suitable format. This will be organized in child issues linked to this epic. ```glql display: table title: Merge requests fields: state, title, assignee, created, updated sort: updated DESC query: type = MergeRequest AND project = "gitlab-org/gitlab" AND id in (220970, 220975, 221007, 221009, 221125, 221132, 221169, 221172, 221211, 221219, 221239, 221274, 221293, 221317, 221319, 221321, 221322, 221323, 221324, 221326, 221328, 221330, 221333, 221335, 221337, 221338, 221340, 221344, 221346, 221360, 221364, 221367, 221380, 221387, 221468, 221563, 222029, 222229, 222230, 222259, 222274, 222321, 222334, 222335, 222431, 222432, 222434, 222437, 222443, 222458, 222460, 222465, 222498, 222724, 222709, 222714, 222920, 222431) ```
