chore: fix README links, add LICENSE, install section

[Vlada-Q]

Two broken links, both from the shared README template.

• [All other integrations here](qonversion.io/integrations) has no scheme. GitHub renders it as a repository-relative path, so on the rendered README it resolves to github.com/qonversion/android-sdk/blob/main/qonversion.io/integrations and 404s. Now https://qonversion.io/integrations (200).
• https://documentation.qonversion.io/discuss-new in Have a question? is left over from readme.io and returns 404 — it is not among the redirects the docs site keeps. That is the link a reader follows when something did not work. It now points at https://qonversion.io/contact-us (200), next to the existing GitHub issues link. The same target is used in the other SDK READMEs so the support channel is one and the same everywhere.

Typo. «paywals» → «paywalls» in the A/B test bullet (it is copied across the READMEs).

No licence text in the repository. The README ends with «Qonversion SDK is available under the MIT license» and carries an MIT badge, but there is no LICENSE file and the GitHub API reports license: null for this repository — so formally the licence exists only as a claim. For a team running a legal review before adopting an SDK, that is a stopper.

Added LICENSE with the MIT text copied from qonversion-ios-sdk, copyright holder unchanged (Qonversion team <hi@qonversion.io>). The badge now links to that file instead of the site's home page (and it used the CocoaPods shield over plain http).

No Installation section. The README goes from «Convinced? Let's go!» straight to Documentation. The Maven coordinates io.qonversion.android.sdk:sdk, the version and minSdkVersion appear nowhere in the file, and there is no link to the Android setup page either — this is the only SDK repository that gives a reader no way at all to install.

Added a short section in the shape of the one in qonversion-ios-sdk: the Gradle coordinates pinned to 9.+ (matching the latest release sdk/9.7.1 and the docs page), minSdkVersion 23 and compileSdk 34 from sdk/build.gradle, a pointer to the releases page, and a link to the Android setup guide.

---

Scope is deliberately narrow: links, licence, install, typo. Positioning, the opening paragraph, the bullets, the banner images and the version badge are untouched — those belong to the README template being rewritten separately.

Document compileSdk 34 in the installation section.

The section documents minSdkVersion 23 but omits compileSdk 34, which is part of the stated installation requirements and the repository build configuration. Add this requirement near Line 209.
