feat: add route option (close #1505)

[Mister-Hope]

Warning

This PR is now based on #1562, so it's expected #1562 to be merged first.

Tip

For a file like /a/b.md, the full format is /a/b.html and clean format is /a/b

Features

This pr adds route option for vuepress config file.

• New route.cleanUrl option to support the "clean format"
• pagePatterns and permalinkPatten is moved to route.pagePatterns and route.permalinkPatten

Bug Fixes

Previously, when use manually set a permalink or page path to a clean format like /a, they will always get 404 when trying to visit the page (in any link format). Now, this is correctly handled. Page path will be normalized to a "full" or "clean" version based on cleanUrl, no matter user use "clean", "full" format or mixing them.

Performance Improvements

Now, the key in routes is always the clean format, which avoid outputting uncessary .html suffix for most pages.

Potential Breaking Changes

• Now inferRoutePath and normalizeRoutePath return the "clean" format instead of "full" format.

Tweaks

Now a new field called routeKey is on the Page object.

now e2e test is added in this PR

A little weird to me, I can not reproduce the CI result locally

@Mister-Hope

In the e2e/docs/components/route-link.md file, the title is Query and hash, but in the e2e/tests/components/route-link.spec.ts file, the locator is：

- .e2e-theme-content #hash-and-query + ul > li a
                      ^^^^^^^^^^^^^^
+ .e2e-theme-content #query-and-hash + ul > li a

which causes the e2e test to fail due to the inability to find the element.

#L94-L100

The regular expression here does not satisfy path matching after enabling cleanUrl. For strings in the format of /xxx, it always returns false, and the value of href in linksPlugin is skipped during parsing, resulting in /xxx instead of /xxx.html.

The regular expression requires that the path part must end with /, .html, or .md, and it is clear that /xxx does not meet this requirement.

[Mister-Hope]

This is excepted, even with cleanUrl, users are required to add .md extension .
