Pull request overview

This PR enables markdown formatting as the default description kind for the entire Scaleway Terraform provider by setting the global schema.DescriptionKind variable to schema.StringMarkdown. This allows provider descriptions, documentation, and help text to be rendered with markdown formatting support.

• Sets schema.DescriptionKind = schema.StringMarkdown to enable markdown descriptions throughout the provider

Setting the global variable schema.DescriptionKind inside ConfigureContextFunc is problematic. This function can be called multiple times (e.g., during provider reconfiguration or in test scenarios), and modifying a global variable inside it could lead to race conditions in concurrent usage scenarios.

The DescriptionKind should be set once during provider initialization, not during configuration. Consider moving this line to execute before the provider is returned, outside of the ConfigureContextFunc. For example, it could be placed right after addBetaResources(p) and before setting p.ConfigureContextFunc.

	p.ConfigureContextFunc = func(ctx context.Context, data *schema.ResourceData) (any, diag.Diagnostics) {
	terraformVersion := p.TerraformVersion
	schema.DescriptionKind = schema.StringMarkdown
	schema.DescriptionKind = schema.StringMarkdown
	p.ConfigureContextFunc = func(ctx context.Context, data *schema.ResourceData) (any, diag.Diagnostics) {
	terraformVersion := p.TerraformVersion
