Issue:
Option to run all commands in script array even if one fails
[poethepoet](https://github.com/nat-n/poethepoet), for example, allows running all scripts even if any fail.  The result code will be 0 only if all succeeded.  This is nice so that you can always see all errors when running multiple linting commands, for example.  It might be nice if hatch eventually had some more advanced functionality like poethepoet for running scripts, but right now this is the only feature I actually care about.

 - Add context formatting functionality i.e. the ability to insert values into configuration like environment variables and command line arguments
 - Add `--show-headers` option to the `env run` command to always display headers, even for single environments
+- Similar to `make`, ignore the exit code of executed commands that start with `-` (a hyphen)
 - Update project metadata to reflect the adoption by PyPA
