[Bug]: Excluding .svg files code is not type safe

[k35o]

Describe the bug

If configured according to this section of the documentation, TypeScript error occurs at this point.

    const imageRule = config.module.rules.find((rule) => rule?.['test']?.test('.svg'));
    if (imageRule) {
      imageRule['exclude'] = /\.svg$/;
    }

Details of the error are as follows.

Element implicitly has an 'any' type because expression of type '"test"' can't be used to index type 'false | "" | 0 | RuleSetRule | "..."'.
  Property 'test' does not exist on type 'false | "" | 0 | RuleSetRule | "..."'.

Element implicitly has an 'any' type because expression of type '"exclude"' can't be used to index type 'RuleSetRule | "..."'.
  Property 'exclude' does not exist on type 'RuleSetRule | "..."'.

Changing to this part would make it typesafe.

    if (imageRule && imageRule !== '...') {
      imageRule['exclude'] = /\.svg$/;
    }

However, I don't know a good moulding for this part(Now it is misguided by any.).

    const imageRule = config.module.rules.find((rule: any) => rule?.['test']?.test('.svg'));
