feat(go): Add context support to all requests (#1527)

## 🧭 What and Why

🎟 JIRA Ticket: https://algolia.atlassian.net/browse/APIC-696

We need to provide a way to accept users' context while respecting general conventions in Go. 

### Changes included:

- Wrapper functions with a `WithContext` suffix added for all API methods to comply with the general DX standards. 
Ex:
```

// CreateAuthentication wraps CreateAuthenticationWithContext using context.Background.
func (c *APIClient) CreateAuthentication(r ApiCreateAuthenticationRequest, opts ...Option) (*AuthenticationCreateResponse, error) {
	return c.CreateAuthenticationWithContext(context.Background(), r, opts...)
}

// @return AuthenticationCreateResponse
func (c *APIClient) CreateAuthenticationWithContext(ctx context.Context, r ApiCreateAuthenticationRequest, opts ...Option) (*AuthenticationCreateResponse, error) {
.
.
.
// actual implementation
}
```
- Playground example added to show context usage. 

## 🧪 Test
Code generation and CI pipeline should be enough.
