fix(frontend): Add custom validator to handle short-text and long-text formats in form renderer (#11395)

The rfjs library was throwing validation errors for our custom format
types `short-text` and `long-text` because these are not standard JSON
Schema formats. This was causing form validation to fail even though
these formats are valid in our application context.

### Changes 🏗️

- Created a custom validator using `@rjsf/validator-ajv8`'s
`customizeValidator` function
- Added support for `short-text` and `long-text` custom formats that
accept any string value
- Replaced the default validator with our custom validator in the
FormRenderer component
- Disabled strict mode and format validation in AJV options to prevent
validation errors for non-standard formats

### Checklist 📋

#### For code changes:
- [x] I have clearly listed my changes in the PR description
- [x] I have made a test plan
- [x] I have tested my changes according to the test plan:
  - [x] Create an agent with input blocks that use short-text format
  - [x] Create an agent with input blocks that use long-text format
  - [x] Execute the agent and verify no validation errors appear
  - [x] Verify that form submission works correctly with both formats
