Fix docs typo WebSecurityConfigurationAdapter->WebSecurityConfigurerAdapter

[him-bhar]

https://docs.spring.io/spring-security/site/docs/current/reference/htmlsingle/#multiple-httpsecurity

Checking latest documentation of spring security, section (6.10) multiple-httpsecurity.

First line says:
We can configure multiple HttpSecurity instances just as we can have multiple blocks. The key is to extend the WebSecurityConfigurationAdapter multiple times.

Whereas, the correct class is WebSecurityConfigurerAdapter.

Can you please correct the documentation to remove this confusion.

@him-bhar is there a reason that you closed the issue?

Would you be interested in submitting a PR with the corrected documentation?

Hello, @jzheaux, I want to participate and submit a PR in documentation. Where can I start?

@kostya05983 thanks for your interest!

You can find the incorrect reference by searching here in GitHub: https://github.com/spring-projects/spring-security/search?q=WebSecurityConfigurationAdapter&unscoped_q=WebSecurityConfigurationAdapter

The PR you'd want to do would be to update that reference in that file to say WebSecurityConfigurerAdapter instead.

There are some general contribution guidelines that should answer any other questions, but please feel free to ping me if anything else isn't clear.

Thanks for response, @jzheaux I submitted a PR.

Sorry guys checked after a long time. I was working on a different version of spring boot. So wasn't sure if class name hasn't actually changed. Looks like initial observation was correct. :)
