Localization: the two getting-started guides are labelled by Editor version ("2019.4+" and "2020.3+") although they teach different workflows, so a new user has no basis for choosing between them

Steps to reproduce:

1. Create a new project with 6000.6.0f1
2. Install the Localization package via "Window > Package Manager"
3. Open the package manual's table of contents at https://docs.unity3d.com/Packages/com.unity.localization@1.5/manual/TableOfContents.html
4. Read the two entries under "Guides" and decide, from those labels alone, which one to follow
5. Open "Quick start guide: 2020.3+" and read the note directly under the heading
6. Open "Quick start guide: 2019.4+" and look for any statement of which Editor versions it covers
7. Compare what each guide actually teaches

Actual results: The "Guides" section offers "Quick start guide: 2019.4+" and "Quick start guide: 2020.3+". Both labels are open-ended, so on any currently supported Editor both apply, and nothing in either label or in the table of contents says how the guides differ.

Neither label references a current stream. The newest Editor version named anywhere in the getting-started section is 2020.3. No Unity 2021, 2022, 2023, Unity 6 or 6000.x appears in either label. A user on 6000.7 is offered two guides scoped to Editors five and six years older than the one they are running, and no guide that claims to cover their own stream.

They are also not version variants of one walkthrough. "Quick Start Guide" teaches the table-based workflow: create an Asset Table Collection and a String Table Collection in the "Localization Tables" window, then add "Localize Texture" and "Localize String" components. "Quick Start Guide with Variants" teaches the Localized Property Variants workflow instead. So the first navigation choice a new user makes is between two different feature sets, presented as a choice between two obsolete Editor versions.

The version scoping is asymmetric on top of that. "Quick Start Guide with Variants" states its own scope in the page body: "This guide requires Unity 2020.3 and above." "Quick Start Guide" carries no version statement anywhere in the page, so its "2019.4+" scoping exists only in the table of contents and is lost entirely when the page is reached from a search result.

Expected results: 

The two getting-started guides are distinguished by the workflow they teach rather than by Editor version, for example "Quick start guide: table-based workflow" and "Quick start guide: property variants workflow". Each guide states its own scope in its page body so it reads correctly when opened directly.

Where the documentation does state Editor version support, it lists the streams the package is actually supported on, including every currently supported LTS release, rather than 2019.4 and 2020.3. A reader on a current LTS should be able to find their own stream named in the documentation instead of inferring coverage from an open-ended "and later".

Reproducible with version: 1.5.13 (6000.6.0f1)
