Spring Security Typo in title of SAML2 Sample Readme

The title of the file samples/boot/saml2login/README.adoc is currently "OAuth 2.0 Login Sample". It should be "SAML 2.0 Login Sample".

Thanks for the report. I saw you sent a pull request at https://github.com/spring-projects/spring-security/pull/8561 but you delete the branch. Any particular reason you did that? Would you be interested in submitting a pull request?

Hi @rwinch , thanks for the response. After I submitted the PR, I realized I wasn't in a position to sign the Contributor License Agreement quite yet. I wasn't exactly sure what the right course of action was.
