Bump fsdocs-tool from 23.0.0-alpha.2 to 23.0.0-alpha.4

[dependabot]

Updated fsdocs-tool from 23.0.0-alpha.2 to 23.0.0-alpha.4.

Release notes

Sourced from fsdocs-tool's releases.

23.0.0-alpha.4

Added

• The "On this page" menu of the default template marks the section the reader is in: the entry of the last heading scrolled past the top of the content gets a coloured left border, and a heading focused with the j / k hotkeys marks its entry as well. Pure CSS, through scroll-driven animations (view-timeline-name, timeline-scope, animation-timeline); browsers without them show the menu as before. The generator numbers the headings and menu entries (data-fsdocs-heading) and emits the wiring in a <style> next to the menu. The colour and the reading line are the --page-menu-active-border-color and --page-menu-reading-line variables. When the menu has its own scroll bar, j / k also scroll the entry of the focused heading into view and put its anchor in the URL (without a history entry). #​1322

• fsdocs watch shows a progress bar along the bottom of the window while it waits for the next page, which can take a while when a big script is rendered for the first time. Dev server only, it comes with the live reload script. #​1322

Fixed

• fsdocs watch renders the API Reference section of the menu with the current _menu_template.html and _menu-item_template.html after an edit; it kept the templates as they were when the watch started, until an assembly changed. #​1323
• The "All Namespaces" entry of the API Reference menu no longer carries the active class on every documentation page when menu templates are used. A page without an entry of its own, such as the docs index, showed it as the current page, and the h hotkey entered the menu there.

23.0.0-alpha.3

Added

• Keyboard navigation in the default template: j / k go to the next / previous heading of the page (or the next / previous link when a menu has the focus), h / l move the focus between the main menu, the content and the page menu. Headings get a visible focus outline and a scroll margin so they are not glued to the top edge. Implemented in the new fsdocs-hotkeys.js, documented under "Keyboard navigation" in the command-line docs.

Fixed

• Link postfix FSharp.Core type constructors (list, option, voption, etc.) in API doc type signatures. Previously only the compiled name form (e.g. FSharpList) was linked; the postfix abbreviation form (e.g. int list) rendered as plain, unlinked text because the abbreviation entity has no TryFullName. The cross-reference resolver now builds the fsharp-core-docs link from the abbreviation's own name (e.g. list → fsharp-collections-list-1) instead of the abbreviated type's compiled name (e.g. FSharpList → fsharp-collections-fsharplist-1, which 404s), falling back to the abbreviated type's definition only for non-generic abbreviations such as string and obj that have no dedicated fsharp-core-docs page. #​1316
