[JS] chore: dependencies cleanup: typescript, teamsfx, and browserify (#2014)

## Linked issues

closes: #1947
closes #1371

#### TLDR: Node 20 is now supported!!! If you're eager for this, you
shouldn't need to wait for a release, as the affected packages were our
samples.

## Details

- Modified package configuration for `typescript` to only allow patch
updates. See Change details below for more information. This is
(ideally) temporary.
- Remove `@microsoft/teamsfx` as a dependency - it turns out this
dependency is entirely unused, but due to sub-dependencies was
preventing us from being able to support Node >=18. Because of this and
`[email protected]` now supporting node 20, teams-ai js package now
also runs with node 20 too!
- Removed `browserify` - unused dependency
- Updated Powered by AI docs to slightly clarify how AI module may use a
`planner`.

#### Change details

[TS made an
update](https://devblogs.microsoft.com/typescript/announcing-typescript-5-6)
that in 5.6 reveals previously 'hidden' TS errors.
`gpt-tokenizer` and `botbuilder` have TS errors that 5.6 catches. I
filed bugs for both packages:
 
[[Bug] Cannot upgrade to TS 5.6x due to build errors · Issue #49 ·
niieani/gpt-tokenizer
(github.com)](niieani/gpt-tokenizer#49)
[Cannot bump typescript to 5.6 due to botbuilder `INodeBuffer` error ·
Issue #4746 · microsoft/botbuilder-js
(github.com)](microsoft/botbuilder-js#4746)
