Neovim version (nvim -v)

0.9.5

Operating system/version

arch linux

Describe the bug

The commit 5aa79935 replaces vim.tbl_islist(args) vim.islist(), which doesn't exist in versions lower than 0.10.0 and therefore breaks the declared compatibility with Neovim >= 0.7.2.

Steps To Reproduce

1. Use any Neovim < 0.10.0 (for example NVIM v0.9.5)
2. Install trouble.nvim
3. Run require "trouble".setup()

Expected Behavior

Either not break compatibility by reverting the change (while being deprecated vim.tbl_islist() still exists), or explicitly declare the new dependency on Neovim >= 0.10.0 in the readme. (+ change the version check in require "trouble".setup().)
