Bump prometheus-net from 7.0.0 to 8.0.0 in /src/Miningcore

[dependabot]

Bumps prometheus-net from 7.0.0 to 8.0.0.

Release notes

Sourced from prometheus-net's releases.

v8.0.0 - OpenMetrics, exemplars, performance optimizations and bugfixes

• Added OpenMetrics exposition format support (#388).
• Added exemplar support for Counter and Histogram (#388).
• The ':' character is no longer allowed in metric or label names. For metric names, Prometheus standard practice is to use colon only in recording rules.
• Publish symbol packages and add Source Link support for easier debugging experience.
• Fix defect where metrics with different labels could overwrite each other in specific circumstances with multiple metric factories in use (#389).
• Ensure even harder that MetricPusher flushes the final state before stopping (#383 and #384)
• Simplify DotNetStats built-in collector code for ease of readability and more best practices (#365, #364)
• Slightly improve Counter performance under concurrent load.
• Reduce memory allocations performed during ASP.NET Core HTTP request tracking.
• By default, EventCounterAdapter will only listen to a small predefined set of general-purpose useful event sources, to minimize resource consumption in the default configuration. A custom event source filter must now be provided to enable listening for additional event sources.
• EventCounterAdapter will only refresh data every 10 seconds by default, to reduce amount of garbage generated in memory (.NET event counters are very noisy and create many temporary objects).
• Added IManagedLifetimeMetricFactory.WithLabels() to enable simpler label enrichment in scenarios where lifetime-managed metric instances are used.
• Added back .NET Standard 2.0 support as some customers had a hard dependency on .NET Standard 2.0 (despite not being a documented feature even earlier).
• Added (Observable)UpDownCounter support to MeterAdapter (.NET 7 specific feature).
