aws-cognito: Add PCRE Regex Validation

[IkeNefcy]

Describe the feature

When creating a userpool using an OICD identity provider, UserPoolIdentityProviderOidc(), The provider name must follow a PCRE convention, which can throw an error in CFN if not matched. CFN displays: /[^_\p{Z}][\p{L}\p{M}\p{S}\p{N}\p{P}][^_\p{Z}]+/ (basically anything, but no spaces, no underscores).
Feature would be to add a type check, or a check during a local build, that shows if the name matches this.

Use Case

Saves time, if a name is passed with "_" or " " (In my case _) then you need to wait for rollback, and depending on how much of the other cognito portions were created, may have to manually delete the user pool that was half created after rollback.

Proposed Solution

Add a Type check, maybe something like

type RegexString<P extends RegExp> = string extends P ? string : string;
const provrule = /[^_\p{Z}][\p{L}\p{M}\p{S}\p{N}\p{P}][^_\p{Z}]+/;
type provname = RegexString<typeof provrule>;

//from cdk /aws-cdk-lib/aws-cognito/lib/user-pool-idps/oidc.d.ts
export interface UserPoolIdentityProviderOidcProps extends UserPoolIdentityProviderProps {
//
// ...
//
     * @default - the unique ID of the construct
     */
    readonly name?: provname;

But this doesn't work with PCRE, if I have time later to get something working I will try, but opening this anyways.

Thanks for the feature request. Linking the documentation referencing the regex pattern you mentioned: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-cognito-userpoolidentityprovider.html
