fix(extras): rename lspconfig.server_configurations to lspconfig.configs (#4518)

## Description


bedb2a0df1
introduces a change to the Lua module structure for `nvim-lspconfig`
that broke `tailwindcss`. Tried to also address all the other usages of
`lspconfig.server_configurations` within the ecosystem.
