`azd env set` does not check for case sensitivity

I was doing an azd env set and typed in AZURE_Location instead of AZURE_LOCATION. I ended up with two entries. We should determine the proper strategy for this, e.g.

• force upper case
• warn if the same value is present but in mixed case
• be case insensitive

I was able to repro this today.

Is this still reproduceable?

@v-xuto can you try to repro?

@rajeshkamal5050 This issue can be reproduced, and we will try to fix it.
