refactor(theme): Sidebar isActive algorithm should be same with Route match

[SoonIter]

Summary

We currently have two matching algorithms for sidebar

{
	'/': [],
	'/guide': [
		{
			text: 'Getting Started',
			link: '/guide/getting-started',
		},
	],
},

1. matchPath(sidebarKey, pathname) in getSidebarGroupData(pathname: string)

decide which sidebarGroup would show, and it will calculate with these keys '/', '/guide' one by one

rspress/packages/theme-default/src/logic/getSidebarDataGroup.ts

Lines 22 to 42 in fb81b99

	*/
	export const matchPath = (
	pattern: string,
	currentPathname: string,
	): boolean => {
	const prefix = withBase(pattern);
	if (prefix === currentPathname) {
	return true;
	}
	const prefixWithTrailingSlash = addTrailingSlash(prefix);
	if (currentPathname.startsWith(prefixWithTrailingSlash)) {
	return true;
	}
	// be compatible with api-extractor
	// '/api/react': [
	// { link: '/api/react.createroot' }
	// ]
	const prefixWithDot = `${prefix}.`;
	return currentPathname.startsWith(prefixWithDot);
	};

2. match(sidebarGroup, pathname)

decide which sidebarItem is active,

to match item.link recursively

{
	text: 'Getting Started',
	link: '/guide/getting-started',
},

some code changes

1. unify all pathname -> routePath logic to pathnameToRouteService

it is a core function which bridge Route and Sidebar

2. use pathnameToRouteService to decide which sidebar is active

Before, we wrote the algorithm repeatedly

This pathnameToRouteService should be the above algorithm 2, it comes froms react-router-dom and already have been used in Route

Of course, Sidebar isActive should use the same logic with Route

3. be compatible to api-extractor generated path

for rspeedy
