chore: bump ElsaVersion and ElsaStudioVersion to 3.8.2

[sfmskywalker]

Bump central Elsa core and Studio package pins from 3.8.1 to 3.8.2 so extensions packages can republish from the correct release/3.8.2 tip against published core + studio 3.8.2.

This is the consumer fix path for #205: the 3.8.1 Mongo/Dapper nupkgs were packed before c9f83e5 / 0619be9, so they do not implement the 3-parameter TryMarkInterruptedAsync added in core 3.8.1. Republishing Mongo/Dapper from this tip with matching 3.8.2 pins lets hosts load against Elsa 3.8.2.

Why

• Core Elsa 3.8.2 and Elsa Studio 3.8.2 are published on nuget.org (Elsa / Elsa.Studio fetchable).
• Extensions still resolve Elsa.* / Elsa.Studio.* via ElsaVersion / ElsaStudioVersion at 3.8.1.
• Same pattern as chore: bump ElsaVersion and ElsaStudioVersion to 3.8.1 #192 (3.8.0 → 3.8.1).

Changes

• Directory.Build.props: ElsaVersion and ElsaStudioVersion 3.8.1 → 3.8.2
• Directory.Packages.props already uses $(ElsaVersion) / $(ElsaStudioVersion); no scattered PackageReference / PackageVersion pins were still hardcoded to 3.8.1
• Left .github/workflows/packages.yml base_version at 3.8.0 (extensions publish version, not an Elsa.* pin). This PR does not retag or publish.

Verify

• dotnet restore Elsa.Extensions.sln succeeded (exit 0)
• Assets resolved Elsa.Workflows.Management/3.8.2 and Elsa.Studio.Workflows/3.8.2 (no leftover Elsa*/3.8.1 in project.assets.json)
• dotnet build of Elsa.Email, Elsa.Studio.WorkflowsContexts, Elsa.Persistence.MongoDb, and Elsa.Persistence.Dapper (net10.0) succeeded with 0 errors
• dotnet test Elsa.MongoDb.UnitTests 27 passed; Elsa.Dapper.UnitTests 16 passed (net10.0)
• Source at this tip already has the 3-parameter TryMarkInterruptedAsync on Mongo + Dapper stores (the 3.8.1 NuGet artifacts are stale: MongoWorkflowInstanceStore / DapperWorkflowInstanceStore don't implement `IWorkflowInstanceStore.TryMarkInterruptedAsync #205 gap is a stale 3.8.1 nupkg, not missing source)

Base tip confirmed: 0619be93 on release/3.8.2.

Code Review — Round 1/4 (tip-bound)

Verdict: APPROVE + HIGH
Tip: 5979edb8cda5a0c59d756bfdf17551096bbaf79d → release/3.8.2
Scope: Directory.Build.props only — ElsaVersion and ElsaStudioVersion 3.8.1 → 3.8.2.

Why APPROVE + HIGH

• Minimal, correct 3.8.2-train republish pin (same pattern as prior ElsaVersion bumps). Directory.Packages.props already uses $(ElsaVersion) / $(ElsaStudioVersion); no leftover hardcoded 3.8.1 PackageVersion pins in that file.
• nuget.org has Elsa / Elsa.Studio / Elsa.Studio.Workflows / Elsa.Api.Client at 3.8.2 — pins are resolvable.
• Patch-safe for release/3.8.2; no code/API surface in this PR. Leaving packages.yml base_version at 3.8.0 is correct (extensions package version, not an Elsa.* pin).
• Human-maintainable: two central properties, no cleverness.

Soft (non-blocking)

• Tip CI when reviewed: GitGuardian + CLA + submit-nuget green. Merge when the suite you treat as required for this branch is green on tip.

Merge gate

Greptile waived on elsa-extensions. Merge on APPROVE+HIGH ∧ CI green.
