build fails with just 1.13.0

$ uname -sm
Darwin arm64
$ just --version
just 1.13.0
$ just compile
error: Expected backtick, identifier, '(', ')', '/', or string, but found '{'

I noticed the issue because I tried tilt up, which uses just

$ tilt up
Tilt started on http://localhost:10350/
v0.32.0, built 2023-03-13

(space) to open the browser
(s) to stream logs (--stream=true)
(t) to open legacy terminal mode (--legacy=true)
(ctrl-c) to exit
Tilt started on http://localhost:10350/
v0.32.0, built 2023-03-13

Regression introduced in #47

Ah, thanks. I must have missed some quotes in there. Did those last end bits rather quickly and the justfile isn't used in CI.
