Update bootstrapped parse-server version and bootstrap.sh script

New Issue Checklist

Issue Description

If I use the official path of installing parse-server by following https://docs.parseplatform.org/parse-server/guide/ it will install verison 3.9.0.

This is inadequate, because it has several security issues (found 28 vulnerabilities (2 low, 11 moderate, 14 high, 1 critical).

Steps to reproduce

sh <(curl -fsSL https://raw.githubusercontent.com/parse-community/parse-server/master/bootstrap.sh)

Also, the bootstrap script doesn't work right as it shows e.g.

\xE2\x9C\x93 node: v10.19.0
instead of
✓ node: v10.19.0

This is because in the bootstrap script echo is called, but it must be echo -e.
Last but not least, the printf in the script should be removed and replaced by the echo command itself. There's no need for printf. If you don't want a newline, just use echo -n.

Start with bootstrap.sh and compare its installed Parse Server version with the version referenced by the Parse Server installation guide. Run the documented bootstrap command to reproduce the escaped checkmark and verify the script's output after updating its version and echo handling.
