Short description of what this resolves:

This commit resolves the desired changes in issue #2335. Change of spellings & font-weight(bold), Pre-selecting Expandable & Open Street Map and getting rid of the "Choose your API version" by setting it to the default v2 as desired.

Though I was not able to deploy the app because to deploy it to either heroku/any other service, either they are paid or need a credit card(for heroku redis) and I don't have that..

Here's the link to the updated app's recording (as suggested): https://open-event-wsgen-2335.vercel.app/248182f3-1663-4b29-b161-e4612701e35d.webm

[One of the solutions to view the code working can be that you can give me a slot in which you'll be reviewing the commit and then I'll be more than happy to attach a link to ngrok so that the commit be tested. Please guide in case any other way out is possible.]

Changes proposed in this pull request:

• Change postion: relative to position: relative,
• Got rid of underscores and bold to unbold,
• Removed the "Choose your API version" and set it default to data.apiVersion= 'api_v2'; in the script,
• As now auto-select to api endpoint has been done, the field to the link of it is also set enabled by default, hence the generate webapp button also. (By script's initialState)

Fixes #2335
