Multilingual Websites: Sidebar Section Alternative Language Key

[infantej2]

Switches to designated language for section titles in the sidebar. If there was no alternative section title, then just uses the original section title. Modify and edit as needed. Please disregard the past commits, only the recent ones are relevant to this PR :)

Here is an example of what it would look in the _quarto.yaml:

sidebar:
    style: "docked"
    logo: "can_wm.png"
    collapse-level: 1
    contents:
      - index.qmd
      - section: "Available Data"
        section-fr: "Available Data (fr)"
        contents:
          - cwfis_datasets.qmd
          - cwfis_map.qmd
          - cwfis_geoserver.qmd
      - usage.qmd
      - section: "Past Map Images"
        section-fr: "Past Map Images (fr)"
        contents:
          - map_images_m3.qmd
          - map_images_fwi.qmd
          - map_images_fbp.qmd
          - map_images_weather.qmd
      - section: "Access Geoserver Layers"
        section-fr: "Access Geoserver Layers (fr)"
        contents:
          - layer_wms.qmd
          - layer_wfs.qmd
          - layer_wcs.qmd

@infantej2 thanks for your contribution. I am not sure I follow what this PR is doing, could you please

• show screenshots of before/after for instance?
• only include relevant commits? a strategy could be to create a fresh new branch off main (after synchronizing your fork), and then cherry pick the relevant commit.

It'd make sense to describe the changes to see whether they fit within the package scope? Thank you!
