[mdatagen] Make display name required in metadata.yaml

[jaydeluca]

The display_name attribute was added in #14115, and I have since gone through and added display names to all core and contrib components.

@mx-psi raised the idea that we could switch this field from optional to required to now ensure all modules going forward include this.

⚠️ Unknown Walltime execution environment detected

Using the Walltime instrument on standard Hosted Runners will lead to inconsistent data.

For the most accurate results, we recommend using CodSpeed Macro Runners: bare-metal machines fine-tuned for performance measurement consistency.

⚠️ Different runtime environments detected

Some benchmarks with significant performance changes were compared across different runtime environments,
which may affect the accuracy of the results.

failing contrib tests show that i missed a few internal components in my pass on contrib, so I will put this into draft and address those first
