[Gitlab.Groups] options should be optional for `share` and `unshare` operations

[loganmzz]

Description

• Node.js version: 24.13.0
• Gitbeaker version: 43.8.0
• Gitbeaker release (cli, rest, core, requester-utils): rest
• OS & version: WSL / Ubuntu 22

For most REST API methods, the options argument is optional. But it's not the case for share and unshare operations on Groups.

Steps to reproduce

const client = new Gitlab(...);
client.Groups.share(group.id, groupToShare.id, AccessLevel.GUEST);
client.Groups.unshare(group.id, groupToShare.id);

Expected behaviour

No compilation error.

Actual behaviour

Expected 4 arguments, but got 3.
index.d.ts(751, 117): An argument for 'options' was not provided.

(method) Groups<false>.share<false>(groupId: string | number, sharedGroupId: string | number, groupAccess: number, options: {
    expiresAt?: string;
} & Sudo & ShowExpanded<false>): Promise<...>

Expected 3 arguments, but got 2.
index.d.ts(759, 98): An argument for 'options' was not provided.

(method) Groups<false>.unshare<false>(groupId: string | number, sharedGroupId: string | number, options: Sudo & ShowExpanded<false>): Promise<void>

Possible fixes

Make options argument optional like for all other methods.
