feat(FR-2107): add version gate for model try content button (#5497)

Resolves #5496 ([FR-2107](https://lablup.atlassian.net/browse/FR-2107))

## Summary
- Add `model-try-content-button` feature flag for manager version >= 26.0.0
- Conditionally render the "Try Content" button in ModelCardModal based on version support

## Test plan
- [ ] Verify the "Try Content" button appears on manager >= 26.0.0
- [ ] Verify the "Try Content" button is hidden on manager < 26.0.0
- [ ] Verify no regression in Model Card modal functionality
