Correct log format for start: parameter

[MikeMcC399]

This PR resolves a log formatting issue when the start: (server) parameter is used.

If a step:

      - name: Cypress run
        uses: cypress-io/github-action@v5
        with:
          start: npm start

is defined in a GitHub workflow, the log would show:

start server "npm start command "npm start"

with the text of the start command incorrectly rendered twice.

The fix is credited to @fbiville who originally submitted PR #481 in Jan, 2022.

With this PR the log output for the above example shows as:

start server command "npm start"

Verification

View the logs of https://github.com/cypress-io/github-action/actions/workflows/example-webpack.yml

Select the wait job then Cypress tests.

Search for "start server" in the log and confirm that:

start server command "npm start"

is shown.

Job 7169797661 shows correct rendering:

start server command "npm start"
current working directory "/home/runner/work/github-action/github-action/examples/webpack"
waiting on "http://localhost:8080" with timeout of 60 seconds
/usr/local/bin/npm start
