chore(release): add LSP plugin extra-files to release-please config

Add 32 LSP plugin plugin.json paths to the root package extra-files in
release-please-config.json so that release-please automatically updates
the version field in each plugin's plugin.json when a root package
release is created.

Previously, only .claude-plugin/plugin.json was listed in extra-files,
requiring manual version management for all LSP plugins.

Plugins added:
- astro-lsp, bash-lsp, biome-lsp, clangd-lsp, csharp-lsp
- dart-lsp, deno-lsp, dockerfile-lsp, elixir-lsp, eslint-lsp
- fsharp-lsp, gleam-lsp, gopls-lsp, graphql-lsp, jdtls-lsp
- kotlin-lsp, lua-lsp, ocaml-lsp, oxlint-lsp, php-lsp
- prisma-lsp, pyright-lsp, rubocop-lsp, rust-analyzer-lsp
- svelte-lsp, swift-lsp, terraform-lsp, texlab-lsp
- typescript-lsp, vue-lsp, yaml-lsp, zls-lsp
