fix(health): redraw after emitting progress message #37567

Problem:
`vim.cmd.redraw()` is not called after displaying a progress message, so
vim will display progress for the previous health check, not the current
one.

Solution:
Call `vim.cmd.redraw()` so that the correct progress message is displayed.
