Describe the bug.

While working on the issue #1621 found that the proxyHost and proxyPort can be passed from arguments but are not read or used. More explanation in the comment. The issue is mainly related to 3 commands [asyncapi validate [SPEC-FILE] [PROXYHOST] [PROXYPORT]] , [asyncapi optimize [SPEC-FILE] [PROXYHOST] [PROXYPORT]] , [asyncapi convert [SPEC-FILE] [PROXYHOST] [PROXYPORT]].

Expected behavior

proxyPort and proxyHost should only be passed via flags.

Screenshots
