fix expect-dap.script for #185 and increase timeout to 10 on expect-dev-entrypoint.script
Closes #185 (closed)
Rewrite of expect-dap.script to retry telnet to debugpy port if it isn't yet running. Also, changed timeout in expect-dev-entrypoint.script from 5 seconds to 10 seconds to allow for slower runners that cannot start a container and run all commands in under 5 seconds.
