Allow using Deno as package manager

[csvn]

Command

new

Description

Add deno as a package manager, such that it can be used during project creation or automatically used when it's lockfile is found.

ng new --package-manager=deno my-project

Deno Details

• Add package command: deno add
• Install all command: deno install
• Lockfile file: deno.lock
• Dev only flag: --dev (e.g. deno add --dev <package(s)>)

Deno seems to have the same commands as the other package manager options, and is similar to pnpm in that it installs packages with symlinks in node_modules.

Describe the solution you'd like

Deno works similar to bun as package manager.

Describe alternatives you've considered

None. If bun is supported, it seems reasonable to support deno too.

[csvn]

Deno also supports the npm_config_user_agent env variable, so it should be possible to automatically use it for installations with @angular/create.
