chore: add sensitive flag for password kind settings

[pnadolny13]

The SDK metadata refresh automation has updated all password kind settings to include the sensitive flag but that doesnt consider non-SDK variants, this PR handles those. We started to get individual PRs like #1693 and #1692 to add the sensitive flag so clearly users are wanting the flag to be updated (presumably to get rid of warning logs) so I figured its good to get all plugins updated.

@edgarrmondragon linting was failing because this touched a bunch of files that havent been touched in a while so the linting rules havent been invoked. The original changes are 3e0fa71 and the lint fixes are from #1697.

Note that unfortunately this won't get rid of the warnings. I logged meltano/meltano#8409.
