Bisq does not allow multiple BTC nodes in the --btcNodes command line parameter

[Akira45-0]

Description

Bisq does not allow multiple BTC nodes in the --btcNodes command line parameter

Version

1.9.19

Steps to reproduce

Run Bisq from command line with more than one server in the btcNodes parameter, for example:
Bisq --btcNodes=2oalsctcn76axnrnaqjddiiu5qhrc7hv3raik2lyfxb7eoktk4vw6sad.onion:8333,ybryiy2k4p4pery4qseap4iu2rxput2akuvpvczwvg4eyfafcdsvyqid.onion:8333

Expected behaviour

Bisq should start and use the servers passed through the btcNodes command line parameter

Actual behaviour

Bisq fails to start. You receive the following error message:
error: problem parsing option 'btcNodes': Found multiple arguments for option btcNodes, but you asked for only one

Additional info

I would like to point out that in line 212 of the Config.java file we can see:
public final String btcNodes;
instead of:
public final List<String> btcNodes;
which may be the cause of this bug.
