template using exec command no-longer working after upgrade to 2024.2.7

[dwooldridge-ctoken]

Describe the bug
Since upgrading from version 2024.1.21 to 2024.2.7 the exec command no-longer works

To Reproduce
Have the following in your .mise.toml:

[env]
GO_VERSION = "{{exec(command='grep \"^go 1\\.[0-9]\\+\\.[0-9]\\+$\" go.mod | cut -f2 -d\" \"')}}"

[tools]
golang = "{{exec(command='grep \"^go 1\\.[0-9]\\+\\.[0-9]\\+$\" go.mod | cut -f2 -d\" \"')}}"

Then run:

mise install
mise failed to resolve tool version: regex parse error:
    ^{{exec(command='grep "^go 1\.[0-9]\+\.[0-9]\+$" go.mod | cut -f2 -d" "')}}([-.].+)?$
      ^

Expected behavior
I expect the golang version to be taken from the go.mod file and GO_VERSION env var to be set to the same value. This used to work with version 2024.1.21

No problems found

Additional context
Maybe there is a better way to achieve this, but I would like to be able to get the go version from the go.mod file AND set the GO_VERSION environment variable so that it can be passed to other tools like just/docker builds etc.

Just to confirm, I reverted back to the older version 2024.1.21 and it works again:

» mise install
mise go@1.21.6 ✓ installed                                                                                                                                        

» mise --version
2024.1.21 linux-x64 (b7e61d6 2024-01-15)

» mise list

» echo $GO_VERSION
