Change bgresponse to js_enabled

[jmctune]

When attempting to authenticate to AWS using GoogleApps SAML, some users are receiving the following error when running the command saml2aws login:

Error authenticating to IdP.: error loading first page: failed to build login form data: could not find any forms matching the provided IDs.

Error page seen when reviewing the response from Google:

Previous workaround was to change the provider from GoogleApps to Browser, but this fix should make this no longer necessary.

Changing the bgresponse from js_disabled to js_enabled has fixed this for myself and a user in my organization.

Looking at resources documented in this repo, I came across the same issue in the aws-google-auth project and the proposed PR to fix. This fix has also worked with this project.

I'm unsure what else these parameters drive, but it hasn't stopped existing users from authenticating either.

Open issues:

• Error authenticating to IdP.: error loading first page: failed to build login form data: could not find any forms matching the provided IDs #750
• Google Apps: could not find any forms matching the provided IDs #493
• Unable to login: "failed to build login form data: could not find any forms matching the provided IDs" #811

Can confirm the fix works for me and other colleagues on both Linux and macOS. Thank you.

I was hoping to confirm can we change the bgresponse value currently on saml2aws version 2.34.0. I am running into the above issue on a VM where I cannot enable the Browser provider.

I tested this change against what's in master and there were no issues, so I imagine you'll be fine with 2.34.0.

Thank you for confirming that @jmctune! I was trying to set the bgresponse field on the .saml2aws configuration, but I was unable to get it to work. My verbose logs always showed the setting to be js_disabled. Is that the correct spot for it? I apologize if the steps have already been elaborated in a ticket. If so, I would really appreciate it if you could attach the ticket number which I could refer to to fix this issue in master.

Thanks @stephanschielke @jmctune ! Figured out what I was doing wrong in my VM. The above solution is working for me as well.

I started getting the dreaded could not find any forms matching the provided IDs. This PR fixed it 👍
This is on Linux.
