Enable gRPC-web dev tools in dev mode for MLMD client

[mturley]

Supports RHOAIENG-7338 and RHOAIENG-7335, but opening this PR separately since it may be generally useful for ongoing dev on other stories as well

Description

In dev mode, enables support for the gRPC-Web Developer Tools browser extension (Chrome install link) (Firefox install link) when initializing the gRPC client for MLMD in PipelinesContext.

This dev tool allows us to view gRPC responses in deserialized JSON instead of base64 encoded binary format. This should make it easier to capture example data for mocks for Cypress tests.

The initialization code comes from the Usage section of the extension's GitHub readme.

How Has This Been Tested?

• Tested that it has no effect when not running in dev mode.
• Tested that it has no effect when the browser extension is not installed.
• Tested that our client's requests are appearing in the extension's log when it is installed.

Test Impact

N/A

Request review criteria:

Self checklist (all need to be checked):

• The developer has manually tested the changes and verified that the changes work
• Commits have been squashed into descriptive, self-contained units of work (e.g. 'WIP' and 'Implements feedback' style messages have been removed)
• Testing instructions have been added in the PR body (for PRs involving changes that are not immediately obvious).
• The developer has added tests or explained why testing cannot be added (unit or cypress tests for related changes)

If you have UI changes:

• Included any necessary screenshots or gifs if it was a UI change.
• Included tags to the UX team if it was a UI/UX change (find relevant UX in the SMEs section).

After the PR is posted & before it merges:

• The developer has tested their solution on a cluster by using the image produced by the PR to main
