This PR is a small change to the documentation when installing OneUptime via docker compose without NPM.

It's preferrable to export the env variables in a subshell because otherwise certain variables such as COMPOSE_PROJECT_NAME will remain in the current shell, causing conflicts with other compose projects for the duration of the session.

For example, after installing OneUptime, I went to go bring up my GitLab compose project and it started using oneuptime as the project name based on the exported COMPOSE_PROJECT_NAME variable.

This had a series of negative consequences:

The docker network was now oneuptime_default instead of gitlab_default
All named volumes were switched from gitlab_volume-name to oneuptime_volume-name.

Afterwards, GitLab was unable to be reached via Caddy due to the network change and it was also detected as a fresh install and made new docker volumes that I now have to go and manually delete.
