PASS_IDENTIFIER and TEAM_IDENTIFIER is not configurable

[D-04]

PASS_IDENTIFIER and TEAM_IDENTIFIER seem to be hardcoded.

covidpass/src/constants.ts

Lines 3 to 4 in 7a9197b

	public static PASS_IDENTIFIER = 'pass.de.marvinsextro.covidpass'
	public static TEAM_IDENTIFIER = 'X8Q7Q2RLTD'

When providing your own Apple Developer certificate Safari will decline the wallet saying: "Safari cannot download this file" since the PASS_IDENTIFIER and TEAM_IDENTIFIER don't match the certificate.

The current workaround for this is adapting these variables by hand and building the repository. However, it would be better if these constants could be configurable through environment variables. These environments variables can then also be set in the docker-compose file.
