[bug fix] do not check version for devbox log, and for commands whose prefix is in the skip-list (#1424)

## Summary

In the generated shellrc file, we invoke `devbox log` to track shell
start times.
```
> git grep "devbox log"
internal/impl/shellrc.tmpl:devbox log shell-ready {{ .ShellStartTime }}
internal/impl/shellrc.tmpl:devbox log shell-interactive {{ .ShellStartTime }}
internal/impl/shellrc_fish.tmpl:devbox log shell-ready {{ .ShellStartTime }}
internal/impl/shellrc_fish.tmpl:devbox log shell-interactive {{ .ShellStartTime }}
```

We should skip checking if devbox version is up-to-date for this case.

Also, made a change to check if the commandPath matches the prefix of
the commandSkipList items. This will #1420

## How was it tested?

Did not test. It compiles.
