Adds Hebrew (he) localization

[Y-PLONI]

Description

Adds a complete Hebrew (he) localization — all 9093 localizable strings, across both catalogs:

File	Entries
package.nls.he.json	2298
l10n/bundle.l10n.he.json	6795

Relates to #577.

The catalogs were produced with the existing scripts/localization-chunks.mjs split/merge workflow, so the keys are byte-identical to the English source (including the non-breaking space in Remote Branch $(git-branch) {0}).

Conventions

l10n/README.md gains a ### Hebrew (he) section next to the existing Spanish and Chinese ones, documenting:

• Glossary — the ~90 git and UI terms, so future contributors stay consistent.
• Register — imperative masculine singular for command, menu and button titles; third-person present for setting descriptions; a verbal noun for Confirm <action> wizard step titles, since those render as dialog headings rather than actions.
• Word order — a Latin brand never leads a Hebrew title or label (מצב Git, not Git מצב), while a full sentence whose subject is the product reads correctly as-is.
• No bidi controls — U+200E/200F and U+202A–202E never appear in a value; the surrounding UI handles direction.
• Distinctions the English preserves and Hebrew must not collapse: fetch vs. pull, discard vs. undo vs. abort, Git config vs. GitLens settings.

Correctness

• All 379 ICU plural blocks keep their structure and use the Hebrew CLDR categories (one/two/many/other) rather than being flattened.
• Placeholders ({0}, {name}), codicons ($(icon-name)), Markdown links and command: URIs are preserved verbatim.
• Git syntax, refs, paths, command ids and product names stay untranslated, per docs/localization.md. Four duration abbreviations ({days}d {hours}h, …) and the two "Inspect"/"Patch" view container titles are deliberately left in Latin.
• pnpm run check and pnpm run test:localization (25/25) both pass.

Notes for maintainers

Two things surfaced during this work that are outside the scope of this PR:

1. RTL layout is not handled. No GitLens webview sets dir="rtl", so with a Hebrew display language the text is Hebrew but the layout stays LTR. Happy to open a separate issue with the specific webviews affected.
2. A handful of English source strings look like typos — an unbalanced {0}}, acccount, layout of **for**, and some eamodio/vscode-gitlens wiki links that now 404. I can file these separately if useful.

The RTL part—it's harder than I initially thought...
If the translation is accepted, I might try to implement it via a series of commits or PRs...

I'm currently working on the RTL part.
