Add Windows (and update Linux) keyring support with zalando/go-keyring

[bkane-msft]

This PR replaces tmc/keyring (who's latest commit was in 2017) with zalando/go-keyring to update go-jira's keyring support.

go-keyring is:

• actively maintained (with the latest update being only 3 days ago)
• used by several projects.
• Allows Windows users to use password-source: keyring
• Updates Linux dbus support ( to godbux/dbus/v5)

This PR is an alternative to #460 (also see #459) for the reasons above and doesn't require @dougEfresh to maintain a fork. I meant to do this far sooner, but my son was born early!

Testing

I tested on MacOS and Windows with the following config:

config:
  stop: true
endpoint: <endpoint-url>
login: <my-username>
user: <my-username>
password-source: keyring 

and the commands:

go run ./cmd/jira login  # prompt to put password in keyring
go run ./cmd/jira logout  # remove stored JIRA session
go run ./cmd/jira login  # retrieve password from keyring and rebuild session

Fixes my issue on MacOS while using keyring and bearer-token
Thanks!
