Hyperlink for formatted cells

[Shelvak]

With this patch we can get the "real hyperlink" doing rows[1,2].hyperlink . And let us add more cell properties in the future.

Fix the original issue gimite#423.

Thanks @y-bonfire for reviving this project.

Thanks for the PR.🤗

The cell class was added spontaneously as a hack, so I feel adding a large number of properties is a bit iffy. However, when it comes to text styling, such as hyperlinks, bold, text color, and background color, a simple array alone feels insufficient.

The 2D array is accessed like a string, but I feel like it should really be a cell object, but that would change things significantly, so it's difficult.
ex.

# write
ws[1,1] = cell.new(text: "xxx", hyperlink:"yyy", background_color: "zzz")

# read
ws[1,1].text
ws[1,1].hyperlink
ws[1,1].background_color

Anyway,
It would be difficult to test if I couldn't not only read but also write, so I added a set function.🤔

I made it so that it can be set like this.

# write
worksheet.set_hyperlink_rich(1,1,1,1, "google", "https://www.google.com/")
worksheet[2,1].set_hyperlink_rich("gemini", "https://gemini.google.com/")

# read
# =>  "https://www.google.com/"
worksheet[1,1].hyperlink

Great job @y-bonfire 🤝

I found the format supported by the Google API.
https://developers.google.com/workspace/sheets/api/reference/rest/v4/spreadsheets/cells#HyperlinkDisplayType

There are a huge number of formatting options.
Wrapping, alignment, padding, styles, rotation, smart tips, etc.
I don't think it's realistic to fully implement and test all of them. Of course, if you're motivated, I'd be happy to do it.♥️

Even if we could do this, there might be some discussion about whether we need charts or pivot tables.
Maybe it would be okay to just do it if there's a request or someone wants to do it.🤔

@y-bonfire yeah, I saw that and that's why I didn't implement the "assign" part, because there's no much need more than read it and assign =HYPERLINK(url, alias).

I don't think we need more magic from a script/background tool. Let's keep it as you did 🤝
Thanks again 👌

Indeed, this worked (although I felt it might not work because it's a formula).🤔

worksheet[1,1] = "=HYPERLINK(\"https://www.google.com/\", \"google\")"
