dont symlink rocks when used in "dev" mode

[teto]

I was trying to debug an issue with https://github.com/neo451/feed.nvim (it creates folders in current directory instead of in stdconfig("data")).

I enabled dev mode with https://github.com/lumen-oss/rocks-dev.nvim:

[plugins."feed.nvim"]
# version = "2.19.2"
dev = true
dir = "/home/teto/neovim/feed.nvim"

and witnessed incoherent behavior (I would remove a file/function yet neovim could still load it).
Turns out neovim would load the code from /home/teto/.local/share/nvim/rocks/rocks_rtp/feed.nvim, done by

rocks.nvim/lua/rocks/adapter.lua

Line 154 in cfacf14

return create_symlink_sync(site_link_dir, rock.name, rock_version_dir)

I am not sure what a proper fix is, can we skip symlinking it if the plugin is in dev mode for instance ?

Not sure if it's the same as #497

lux.nvim won't be doing any symlink shenanigans, so this will be fixed when we've completed the migration (vhyrro is working on it as we speak 😄).
