refactor: replace deprecated vim.loop with vim.uv

[broken-pen]

Summary

Replace vim.loop with vim.uv. The former has been deprecated since 0.10, which is our minimum version, as far as I can tell.

Changes

• replaced vim.loop with vim.uv in manual search & replace
• scripts/minimal_init.lua also had its quotes changed by Stylua
• Running Stylua inside scripts/ produced a lot of changes; I left those in other files out to avoid cluttering the diff.
• There are two files¹ with lines local uv = vim.loop at the top, that now read local uv = vim.uv. I'm not sure about the purpose of these (in Python, you'd do this to avoid repeated attribute lookups, which can be costly), so I left them as is.
• where those files still used vim.loop, I replaced it with uv, not vim.uv for consistency
