Update metadate (title and meta description) of the Core Development page
Hi, it seems that the metadata (title and meta description) for the Core Development at https://typo3.org/community/teams/typo3-development is outdated: In still mentions the "Core Development Team", but according to https://typo3.org/article/a-revised-core-development-structure (and according to Benni), there is no Core Development Team anymore (since 2019). (There are some roles ("merger") which people hold (without forming a team).) The metadata also is what shows up on the team list page https://typo3.org/community/teams and on Google search results, so I think updating this helps avoid confusion.
