TM_ORG_URL should include http:// or https://

[frafra]

I updated the tasking manager on a server, and I found it was generating a broken link in the header.

This is because the example.env specifies that TM_ORG_URL and TM_ORG_PRIVACY_POLICY_URL should not include the protocol:

tasking-manager/example.env

Lines 26 to 28 in 32077cf

	# Don't use http or https on the following two variables
	TM_ORG_URL=example.com
	TM_ORG_PRIVACY_POLICY_URL=https://www.hotosm.org/privacy

This is not correct, since the frontend does not add the protocol:

tasking-manager/frontend/src/components/header/index.js

Line 103 in 32077cf

<a className="link red f6 mr2" href={`${ORG_URL}`} target="_blank" rel="noreferrer">

This is because of a change that has not been reflected in the example file:
