chore: update Azle templates to 0.25.0

[lastmjs]

Description

Please include a summary of the change and which issue is fixed. Please also include relevant motivation and context.

The dfx new command for Azle has been out-of-date for a while now. This PR updates Azle's templates to the latest version and simplifies the templates with new changes possible because of the latest version.

How Has This Been Tested?

I built the sdk locally and manually used the dfx new command to create a new example project. I then deployed the project and checked that it worked in the Candid UI.

Checklist:

• The title of this PR complies with Conventional Commits. (From @lastmjs Is this considered a breaking change?)
• I have edited the CHANGELOG accordingly. (From @lastmjs do I need to edit the CHANGELOG?)
• I have made corresponding changes to the documentation. (From @lastmjs Azle's documentation in DFINITY's web properties is generally out-of-date...I hear that soon DFINITY will simply point to Demergent Labs' documentation)

The following fails, because with this setup the backend canister (type=azle) is relying on a frontend canister to run npm install to install the azle extension.

It might be enough for this specific case to move the npm install post_create setup in templates.js to the dfx_js_base template.

Even then, if npm install fails (and notice that dfx new is specifically set up to treat this as a warning), all dfx commands run in the project will report an error like the one below until npm install is run and succeeds.

$ dfx cache delete
$ dfx new azt --type azle --frontend none

$ cd azt
$ dfx deploy
Error: Failed to create AgentEnvironment.
Caused by: canister 'azt_backend' has unknown type 'azle' and there is no installed extension by that name which could define it

It might be enough for this specific case to move the npm install post_create setup in templates.js to the dfx_js_base template.

I assume you meant templates.rs. I have attempted to do what you've described here, as well as updating Azle to its latest 0.25.0.

[ericswanson-dfinity]

This should remove the post create fields from the templates that require dfx_js_base, and add them here.

I believe I have done this correctly now
