Keymapping which utilizes multiple commands doesn't work in 0.5

[raygervais]

Reproduction steps

• Edit ~/.config/helix/config.toml to include the following

[keys.normal]
"ret" = ["open_below", "normal_mode"] # Maps the enter key to open_below then re-enter normal mode

• Open helix, note the error:

Error: data did not match any variant of untagged enum KeyTrie for key `keys.normal` at line 7 column 1

Sample Config for context:

theme = "everforest"

[lsp]
display-messages = true
line-numbers = "relative"

[keys.normal]
g = { a = "code_action" } # <- Works, but if I were to add additional commands such as below, fails.
"ret" = ["open_below", "normal_mode"] # Does not work

Environment

• Platform: MacOS
• Helix version: helix 0.5.0

~/.cache/helix/helix.log

You will have to build from master for it to work since it was merged after the 0.5 release (#589).

\cc @archseer We should probably host docs for both tagged releases and master to avoid confusion.
