Update solver_specific example due to failure

[arnavk23]

@tmigot The rendering failure was caused by the newly added example in the solver_specific section: calling bmark_solvers in this environment triggers UndefVarError: reset! during weaving, which then broke the generated page content. I reproduced this locally from the same weave/parse pipeline and confirmed the failing error block in index.md:560

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Updates the tutorial example for solver-specific statistics to use a minimal ADNLPModels-based setup instead of running a full benchmark over NLPModelsTest problems.

Changes:

• Replaced the benchmark-based example (bmark_solvers, NLPModelsTest.BROWNDEN()) with a simple ADNLPModel and direct GenericExecutionStats usage.
• Removed DataFrames/NLPModelsTest/SolverBenchmark imports from the example snippet.
• Updated the demonstration output to show stats.solver_specific directly.

This is a SolverBenchmark documentation, so I don't understand how removing this package will help?

This is what we should be looking at

But currently we see

Error: UndefVarError: `reset!` not defined in `SolverBenchmark`

I agree with your comment here and think the example is solid so just added for the reset! to pass. Why make a big change when the example we agreed on gives everything a user needs to go through the function implementation.
